@cindex Making Frr
There are three steps for installing the software: configuration,
compilation, and installation.

The easiest way to get Frr running is to issue the following
commands:
@example
% configure
% make
% make install

@subsection The Configure script and its options
@cindex Configuration options
@cindex Options for configuring
@cindex Build options
@cindex Distribution configuration
@cindex Options to @code{./configure}
Frr has an excellent configure script which automatically detects most
host configurations. There are several additional configure options to
customize the build to include or exclude specific features and dependencies.
@table @option
@item --disable-zebra
Do not build zebra daemon.
@item --disable-ripd
Do not build ripd.
@item --disable-ripngd
Do not build ripngd.
@item --disable-ospfd
Do not build ospfd.
@item --disable-ospf6d
Do not build ospf6d.
@item --disable-bgpd
Do not build bgpd.
@item --disable-bgp-announce
Make @command{bgpd} which does not make bgp announcements at all. This
feature is good for using @command{bgpd} as a BGP announcement listener.
@item --enable-datacenter
Enable system defaults to work as if in a Data Center. See defaults.h
for what is changed by this configure option.
@item --enable-snmp
Enable SNMP support. By default, SNMP support is disabled.
@item --disable-ospfapi
Disable support for OSPF-API, an API to interface directly with ospfd.
OSPF-API is enabled if --enable-opaque-lsa is set.
@item --disable-ospfclient
Disable building of the example OSPF-API client.
@item --disable-ospf-ri
Disable support for OSPF Router Information (RFC4970 & RFC5088) this
requires support for Opaque LSAs and Traffic Engineering.
@item --disable-isisd
Do not build isisd.
@item --enable-isis-topology
Enable IS-IS topology generator.
@item --enable-isis-te
Enable Traffic Engineering Extension for ISIS (RFC5305)
@item --enable-multipath=@var{ARG}
Enable support for Equal Cost Multipath. @var{ARG} is the maximum number
of ECMP paths to allow, set to 0 to allow unlimited number of paths.
@item --enable-realms
Enable the support of linux Realms. Convert tag values from 1-255
into a realm value when inserting into the linux kernel. Then
routing policy can be assigned to the realm. See the tc man page.
@item --disable-rtadv
Disable support IPV6 router advertisement in zebra.
@item --enable-gcc-rdynamic
Pass the @command{-rdynamic} option to the linker driver. This is in most
cases neccessary for getting usable backtraces. This option defaults to on
if the compiler is detected as gcc, but giving an explicit enable/disable is
suggested.
@item --disable-backtrace
Controls backtrace support for the crash handlers. This is autodetected by
default. Using the switch will enforce the requested behaviour, failing with
an error if support is requested but not available. On BSD systems, this
needs libexecinfo, while on glibc support for this is part of libc itself.
@item --enable-dev-build
Turn on some options for compiling FRR within a development environment in
mind. Specifically turn on -g3 -O0 for compiling options and add inclusion
of grammar sandbox.
@item --enable-fuzzing
Turn on some compile options to allow you to run fuzzing tools
against the system. This tools is intended as a developer
only tool and should not be used for normal operations
@end table
You may specify any combination of the above options to the configure
script. By default, the executables are placed in @file{/usr/local/sbin}
and the configuration files in @file{/usr/local/etc}. The @file{/usr/local/}
installation prefix and other directories may be changed using the following
options to the configuration script.
@table @option
@item --prefix=@var{prefix}
Install architecture-independent files in @var{prefix} [/usr/local].
@item --sysconfdir=@var{dir}
Look for configuration files in @var{dir} [@var{prefix}/etc]. Note
that sample configuration files will be installed here.
@item --localstatedir=@var{dir}
Configure zebra to use @var{dir} for local state files, such
as pid files and unix sockets.
@end table
@example
% ./configure --disable-snmp
@end example
This command will configure zebra and the routing daemons.
@node Least-Privilege support
@subsection Least-Privilege support
@cindex Frr Least-Privileges
@cindex Frr Privileges
Additionally, you may configure zebra to drop its elevated privileges
shortly after startup and switch to another user. The configure script will
automatically try to configure this support. There are three configure
options to control the behaviour of Frr daemons.
@table @option
@item --enable-user=@var{user}
Switch to user @var{ARG} shortly after startup, and run as user @var{ARG}
in normal operation.
@item --enable-group=@var{group}
Switch real and effective group to @var{group} shortly after
startup.
@item --enable-vty-group=@var{group}
Create Unix Vty sockets (for use with vtysh) with group owndership set to
@var{group}. This allows one to create a seperate group which is
restricted to accessing only the Vty sockets, hence allowing one to
delegate this group to individual users, or to run vtysh setgid to
this group.
@end table
The default user and group which will be configured is 'frr' if no user
or group is specified. Note that this user or group requires write access to
the local state directory (see --localstatedir) and requires at least read
access, and write access if you wish to allow daemons to write out their
configuration, to the configuration directory (see --sysconfdir).
On systems which have the 'libcap' capabilities manipulation library
(currently only linux), the frr system will retain only minimal
capabilities required, further it will only raise these capabilities for
brief periods. On systems without libcap, frr will run as the user
specified and only raise its uid back to uid 0 for brief periods.
@node Linux notes
@subsection Linux Notes
@cindex Configuring Frr
@cindex Building on Linux boxes
@cindex Linux configurations
There are several options available only to @sc{gnu}/Linux systems:
@footnote{@sc{gnu}/Linux has very flexible kernel configuration features}. If
you use @sc{gnu}/Linux, make sure that the current kernel configuration is
what you want. Frr will run with any kernel configuration but some
recommendations do exist.
@table @var
@item CONFIG_NETLINK
Kernel/User netlink socket. This is a brand new feature which enables an
advanced interface between the Linux kernel and zebra (@pxref{Kernel Interface}).
@item CONFIG_RTNETLINK
Routing messages.
This makes it possible to receive netlink routing messages. If you
specify this option, @command{zebra} can detect routing information
updates directly from the kernel (@pxref{Kernel Interface}).
@item CONFIG_IP_MULTICAST
IP: multicasting.
This option should be specified when you use @command{ripd} (@pxref{RIP}) or
@command{ospfd} (@pxref{OSPFv2}) because these protocols use multicast.
@end table
IPv6 support has been added in @sc{gnu}/Linux kernel version 2.2. If you
try to use the Frr IPv6 feature on a @sc{gnu}/Linux kernel, please
make sure the following libraries have been installed. Please note that
these libraries will not be needed when you uses @sc{gnu} C library 2.1
or upper.
@table @code
@item inet6-apps
The @code{inet6-apps} package includes basic IPv6 related libraries such
as @code{inet_ntop} and @code{inet_pton}. Some basic IPv6 programs such
as @command{ping}, @command{ftp}, and @command{inetd} are also
included. The @code{inet-apps} can be found at
@uref{ftp://ftp.inner.net/pub/ipv6/}.
@item net-tools
The @code{net-tools} package provides an IPv6 enabled interface and
routing utility. It contains @command{ifconfig}, @command{route},
@command{netstat}, and other tools. @code{net-tools} may be found at
@uref{http://www.tazenda.demon.co.uk/phil/net-tools/}.
@end table
@c A - end of footnote
@node Build the Software
@section Build the Software
After configuring the software, you will need to compile it for your
system. Simply issue the command @command{make} in the root of the source
directory and the software will be compiled. Cliff Note versions of
different compilation examples can be found in the doc/Building_FRR_on_XXX.md
files. If you have *any* problems at this stage, be certain to send a
bug report @xref{Bug Reports}.
@example
% ./bootstrap.sh
% ./configure <appropriate to your system>
% make
@end example
@c A - End of node, Building the Software
@node Install the Software
@comment node-name, next, previous, up
@section Install the Software
Installing the software to your system consists of copying the compiled
programs and supporting files to a standard location. After the
installation process has completed, these files have been copied
from your work directory to @file{/usr/local/bin}, and @file{/usr/local/etc}.
To install the Frr suite, issue the following command at your shell
prompt: @command{make install}.
@example
%
% make install
%
@end example
Frr daemons have their own terminal interface or VTY. After
installation, you have to setup each beast's port number to connect to
them. Please add the following entries to @file{/etc/services}.
@example
zebrasrv 2600/tcp # zebra service
zebra 2601/tcp # zebra vty
ripd 2602/tcp # RIPd vty
ripngd 2603/tcp # RIPngd vty
ospfd 2604/tcp # OSPFd vty
bgpd 2605/tcp # BGPd vty
ospf6d 2606/tcp # OSPF6d vty
ospfapi 2607/tcp # ospfapi
isisd 2608/tcp # ISISd vty
nhrpd 2610/tcp # nhrpd vty
pimd 2611/tcp # PIMd vty
@end example
If you use a FreeBSD newer than 2.2.8, the above entries are already
added to @file{/etc/services} so there is no need to add it. If you
specify a port number when starting the daemon, these entries may not be
needed.
You may need to make changes to the config files in
@file{@value{INSTALL_PREFIX_ETC}/*.conf}. @xref{Config Commands}.

@node ISIS
@chapter ISIS
@acronym{ISIS,Intermediate System to Intermediate System} is a routing protocol
which is described in @cite{ISO10589, RFC1195, RFC5308}. ISIS is an
@acronym{IGP,Interior Gateway Protocol}. Compared with @acronym{RIP},
@acronym{ISIS} can provide scalable network support and faster
convergence times like @acronym{OSPF}. ISIS is widely used in large networks such as
@acronym{ISP,Internet Service Provider} and carrier backbone networks.

@node Configuring isisd
@section Configuring isisd
There are no @command{isisd} specific options. Common options can be
specified (@pxref{Common Invocation Options}) to @command{isisd}.
@command{isisd} needs to acquire interface information from
@command{zebra} in order to function. Therefore @command{zebra} must be
running before invoking @command{isisd}. Also, if @command{zebra} is
restarted then @command{isisd} must be too.
Like other daemons, @command{isisd} configuration is done in @acronym{ISIS}
specific configuration file @file{isisd.conf}.

@chapter OSPFv2
@acronym{OSPF,Open Shortest Path First} version 2 is a routing protocol
which is described in @cite{RFC2328, OSPF Version 2}. OSPF is an
@acronym{IGP,Interior Gateway Protocol}. Compared with @acronym{RIP},
@acronym{OSPF} can provide scalable network support and faster
convergence times. OSPF is widely used in large networks such as
@acronym{ISP,Internet Service Provider} backbone and enterprise
networks.

@node Configuring ospfd
@section Configuring ospfd
There are no @command{ospfd} specific options. Common options can be
specified (@pxref{Common Invocation Options}) to @command{ospfd}.
@command{ospfd} needs to acquire interface information from
@command{zebra} in order to function. Therefore @command{zebra} must be
running before invoking @command{ospfd}. Also, if @command{zebra} is
restarted then @command{ospfd} must be too.
Like other daemons, @command{ospfd} configuration is done in @acronym{OSPF}
specific configuration file @file{ospfd.conf}.
@node OSPF router
@section OSPF router
To start OSPF process you have to specify the OSPF router. As of this
writing, @command{ospfd} does not support multiple OSPF processes.
@deffn Command {router ospf} {}
@deffnx Command {no router ospf} {}
Enable or disable the OSPF process. @command{ospfd} does not yet
support multiple OSPF processes. So you can not specify an OSPF process
number.
@end deffn
@deffn {OSPF Command} {ospf router-id @var{a.b.c.d}} {}
@deffnx {OSPF Command} {no ospf router-id} {}
@anchor{ospf router-id}This sets the router-ID of the OSPF process. The
router-ID may be an IP address of the router, but need not be - it can
be any arbitrary 32bit number. However it MUST be unique within the
entire OSPF domain to the OSPF speaker - bad things will happen if
multiple OSPF speakers are configured with the same router-ID! If one
is not specified then @command{ospfd} will obtain a router-ID
automatically from @command{zebra}.
@end deffn
@deffn {OSPF Command} {ospf abr-type @var{type}} {}
@deffnx {OSPF Command} {no ospf abr-type @var{type}} {}
@var{type} can be cisco|ibm|shortcut|standard. The "Cisco" and "IBM" types
are equivalent.
The OSPF standard for ABR behaviour does not allow an ABR to consider
routes through non-backbone areas when its links to the backbone are
down, even when there are other ABRs in attached non-backbone areas
which still can reach the backbone - this restriction exists primarily
to ensure routing-loops are avoided.
With the "Cisco" or "IBM" ABR type, the default in this release of
Frr, this restriction is lifted, allowing an ABR to consider
summaries learnt from other ABRs through non-backbone areas, and hence
route via non-backbone areas as a last resort when, and only when,
backbone links are down.
Note that areas with fully-adjacent virtual-links are considered to be
"transit capable" and can always be used to route backbone traffic, and
hence are unaffected by this setting (@pxref{OSPF virtual-link}).
More information regarding the behaviour controlled by this command can
be found in @cite{RFC 3509, Alternative Implementations of OSPF Area
Border Routers}, and @cite{draft-ietf-ospf-shortcut-abr-02.txt}.
Quote: "Though the definition of the @acronym{ABR,Area Border Router}
in the OSPF specification does not require a router with multiple
attached areas to have a backbone connection, it is actually
necessary to provide successful routing to the inter-area and
external destinations. If this requirement is not met, all traffic
destined for the areas not connected to such an ABR or out of the
OSPF domain, is dropped. This document describes alternative ABR
behaviors implemented in Cisco and IBM routers."
@end deffn
@deffn {OSPF Command} {ospf rfc1583compatibility} {}
@deffnx {OSPF Command} {no ospf rfc1583compatibility} {}
@cite{RFC2328}, the sucessor to @cite{RFC1583}, suggests according
to section G.2 (changes) in section 16.4 a change to the path
preference algorithm that prevents possible routing loops that were
possible in the old version of OSPFv2. More specifically it demands
that inter-area paths and intra-area backbone path are now of equal preference
but still both preferred to external paths.
This command should NOT be set normally.
@end deffn
@deffn {OSPF Command} {log-adjacency-changes [detail]} {}
@deffnx {OSPF Command} {no log-adjacency-changes [detail]} {}
Configures ospfd to log changes in adjacency. With the optional
detail argument, all changes in adjacency status are shown. Without detail,
only changes to full or regressions are shown.
@end deffn
@deffn {OSPF Command} {passive-interface @var{interface}} {}
@deffnx {OSPF Command} {no passive-interface @var{interface}} {}
@anchor{OSPF passive-interface} Do not speak OSPF interface on the
given interface, but do advertise the interface as a stub link in the
router-@acronym{LSA,Link State Advertisement} for this router. This
allows one to advertise addresses on such connected interfaces without
having to originate AS-External/Type-5 LSAs (which have global flooding
scope) - as would occur if connected addresses were redistributed into
OSPF (@pxref{Redistribute routes to OSPF})@. This is the only way to
advertise non-OSPF links into stub areas.
@end deffn
@deffn {OSPF Command} {timers throttle spf @var{delay} @var{initial-holdtime} @var{max-holdtime}} {}
@deffnx {OSPF Command} {no timers throttle spf} {}
This command sets the initial @var{delay}, the @var{initial-holdtime}
and the @var{maximum-holdtime} between when SPF is calculated and the
event which triggered the calculation. The times are specified in
milliseconds and must be in the range of 0 to 600000 milliseconds.
The @var{delay} specifies the minimum amount of time to delay SPF
calculation (hence it affects how long SPF calculation is delayed after
an event which occurs outside of the holdtime of any previous SPF
calculation, and also serves as a minimum holdtime).
Consecutive SPF calculations will always be seperated by at least
'hold-time' milliseconds. The hold-time is adaptive and initially is
set to the @var{initial-holdtime} configured with the above command.
Events which occur within the holdtime of the previous SPF calculation
will cause the holdtime to be increased by @var{initial-holdtime}, bounded
by the @var{maximum-holdtime} configured with this command. If the adaptive
hold-time elapses without any SPF-triggering event occuring then
the current holdtime is reset to the @var{initial-holdtime}. The current
holdtime can be viewed with @ref{show ip ospf}, where it is expressed as
a multiplier of the @var{initial-holdtime}.
@example
@group
router ospf
timers throttle spf 200 400 10000
@end group
@end example
In this example, the @var{delay} is set to 200ms, the @var{initial
holdtime} is set to 400ms and the @var{maximum holdtime} to 10s. Hence
there will always be at least 200ms between an event which requires SPF
calculation and the actual SPF calculation. Further consecutive SPF
calculations will always be seperated by between 400ms to 10s, the
hold-time increasing by 400ms each time an SPF-triggering event occurs
within the hold-time of the previous SPF calculation.
This command supercedes the @command{timers spf} command in previous Frr
releases.
@end deffn
@deffn {OSPF Command} {max-metric router-lsa [on-startup|on-shutdown] <5-86400>} {}
@deffnx {OSPF Command} {max-metric router-lsa administrative} {}
@deffnx {OSPF Command} {no max-metric router-lsa [on-startup|on-shutdown|administrative]} {}
This enables @cite{RFC3137, OSPF Stub Router Advertisement} support,
where the OSPF process describes its transit links in its router-LSA as
having infinite distance so that other routers will avoid calculating
transit paths through the router while still being able to reach
networks through the router.
This support may be enabled administratively (and indefinitely) or
conditionally. Conditional enabling of max-metric router-lsas can be
for a period of seconds after startup and/or for a period of seconds
prior to shutdown.
Enabling this for a period after startup allows OSPF to converge fully
first without affecting any existing routes used by other routers,
while still allowing any connected stub links and/or redistributed
routes to be reachable. Enabling this for a period of time in advance
of shutdown allows the router to gracefully excuse itself from the OSPF
domain.
Enabling this feature administratively allows for administrative
intervention for whatever reason, for an indefinite period of time.
Note that if the configuration is written to file, this administrative
form of the stub-router command will also be written to file. If
@command{ospfd} is restarted later, the command will then take effect
until manually deconfigured.
Configured state of this feature as well as current status, such as the
number of second remaining till on-startup or on-shutdown ends, can be
viewed with the @ref{show ip ospf} command.
@end deffn
@deffn {OSPF Command} {auto-cost reference-bandwidth <1-4294967>} {}
@deffnx {OSPF Command} {no auto-cost reference-bandwidth} {}
@anchor{OSPF auto-cost reference-bandwidth}This sets the reference
bandwidth for cost calculations, where this bandwidth is considered
equivalent to an OSPF cost of 1, specified in Mbits/s. The default is
100Mbit/s (i.e. a link of bandwidth 100Mbit/s or higher will have a
cost of 1. Cost of lower bandwidth links will be scaled with reference
to this cost).
This configuration setting MUST be consistent across all routers within the
OSPF domain.
@end deffn
@deffn {OSPF Command} {network @var{a.b.c.d/m} area @var{a.b.c.d}} {}
@deffnx {OSPF Command} {network @var{a.b.c.d/m} area @var{<0-4294967295>}} {}
@deffnx {OSPF Command} {no network @var{a.b.c.d/m} area @var{a.b.c.d}} {}
@deffnx {OSPF Command} {no network @var{a.b.c.d/m} area @var{<0-4294967295>}} {}
@anchor{OSPF network command}
This command specifies the OSPF enabled interface(s). If the interface has
an address from range 192.168.1.0/24 then the command below enables ospf
on this interface so router can provide network information to the other
ospf routers via this interface.
@example
@group
router ospf
network 192.168.1.0/24 area 0.0.0.0
@end group
@end example
Prefix length in interface must be equal or bigger (ie. smaller network) than
prefix length in network statement. For example statement above doesn't enable
ospf on interface with address 192.168.1.1/23, but it does on interface with
address 192.168.1.129/25.
Note that the behavior when there is a peer address
defined on an interface changed after release 0.99.7.
Currently, if a peer prefix has been configured,
then we test whether the prefix in the network command contains
the destination prefix. Otherwise, we test whether the network command prefix
contains the local address prefix of the interface.
In some cases it may be more convenient to enable OSPF on a per
interface/subnet basis (@pxref{OSPF ip ospf area command}).
@end deffn
@node OSPF area
@section OSPF area
@deffn {OSPF Command} {area @var{a.b.c.d} range @var{a.b.c.d/m}} {}
@deffnx {OSPF Command} {area <0-4294967295> range @var{a.b.c.d/m}} {}
@deffnx {OSPF Command} {no area @var{a.b.c.d} range @var{a.b.c.d/m}} {}
@deffnx {OSPF Command} {no area <0-4294967295> range @var{a.b.c.d/m}} {}
Summarize intra area paths from specified area into one Type-3 summary-LSA
announced to other areas. This command can be used only in ABR and ONLY
router-LSAs (Type-1) and network-LSAs (Type-2) (ie. LSAs with scope area) can
be summarized. Type-5 AS-external-LSAs can't be summarized - their scope is AS.
Summarizing Type-7 AS-external-LSAs isn't supported yet by Frr.
@example
@group
router ospf
network 192.168.1.0/24 area 0.0.0.0
network 10.0.0.0/8 area 0.0.0.10
area 0.0.0.10 range 10.0.0.0/8
@end group
@end example
With configuration above one Type-3 Summary-LSA with routing info 10.0.0.0/8 is
announced into backbone area if area 0.0.0.10 contains at least one intra-area
network (ie. described with router or network LSA) from this range.
@end deffn
@deffn {OSPF Command} {area @var{a.b.c.d} range IPV4_PREFIX not-advertise} {}
@deffnx {OSPF Command} {no area @var{a.b.c.d} range IPV4_PREFIX not-advertise} {}
Instead of summarizing intra area paths filter them - ie. intra area paths from this
range are not advertised into other areas.
This command makes sense in ABR only.
@end deffn
@deffn {OSPF Command} {area @var{a.b.c.d} range IPV4_PREFIX substitute IPV4_PREFIX} {}
@deffnx {OSPF Command} {no area @var{a.b.c.d} range IPV4_PREFIX substitute IPV4_PREFIX} {}
Substitute summarized prefix with another prefix.
@example
@group
router ospf
network 192.168.1.0/24 area 0.0.0.0
network 10.0.0.0/8 area 0.0.0.10
area 0.0.0.10 range 10.0.0.0/8 substitute 11.0.0.0/8
@end group
@end example
One Type-3 summary-LSA with routing info 11.0.0.0/8 is announced into backbone area if
area 0.0.0.10 contains at least one intra-area network (ie. described with router-LSA or
network-LSA) from range 10.0.0.0/8.
This command makes sense in ABR only.
@end deffn
@deffn {OSPF Command} {area @var{a.b.c.d} virtual-link @var{a.b.c.d}} {}

@deffnx {OSPF Command} {no area @var{a.b.c.d} shortcut} {}
@deffnx {OSPF Command} {no area <0-4294967295> shortcut} {}
Configure the area as Shortcut capable. See @cite{RFC3509}. This requires
that the 'abr-type' be set to 'shortcut'.
@end deffn
@deffn {OSPF Command} {area @var{a.b.c.d} stub} {}
@deffnx {OSPF Command} {area <0-4294967295> stub} {}
@deffnx {OSPF Command} {no area @var{a.b.c.d} stub} {}
@deffnx {OSPF Command} {no area <0-4294967295> stub} {}
Configure the area to be a stub area. That is, an area where no router
originates routes external to OSPF and hence an area where all external
routes are via the ABR(s). Hence, ABRs for such an area do not need
to pass AS-External LSAs (type-5s) or ASBR-Summary LSAs (type-4) into the
area. They need only pass Network-Summary (type-3) LSAs into such an area,
along with a default-route summary.
@end deffn

@deffnx {OSPF Command} {area <0-4294967295> stub no-summary} {}
@deffnx {OSPF Command} {no area @var{a.b.c.d} stub no-summary} {}
@deffnx {OSPF Command} {no area <0-4294967295> stub no-summary} {}
Prevents an @command{ospfd} ABR from injecting inter-area
summaries into the specified stub area.
@end deffn
@deffn {OSPF Command} {area @var{a.b.c.d} default-cost <0-16777215>} {}

@deffnx {OSPF Command} {no area @var{a.b.c.d} export-list NAME} {}
@deffnx {OSPF Command} {no area <0-4294967295> export-list NAME} {}
Filter Type-3 summary-LSAs announced to other areas originated from intra-
area paths from specified area.
@example
@group
router ospf
network 192.168.1.0/24 area 0.0.0.0
network 10.0.0.0/8 area 0.0.0.10
area 0.0.0.10 export-list foo
!
access-list foo permit 10.10.0.0/16
access-list foo deny any
@end group
@end example
With example above any intra-area paths from area 0.0.0.10 and from range
10.10.0.0/16 (for example 10.10.1.0/24 and 10.10.2.128/30) are announced into
other areas as Type-3 summary-LSA's, but any others (for example 10.11.0.0/16
or 10.128.30.16/30) aren't.
This command is only relevant if the router is an ABR for the specified
area.
@end deffn
@deffn {OSPF Command} {area @var{a.b.c.d} import-list NAME} {}
@deffnx {OSPF Command} {area <0-4294967295> import-list NAME} {}
@deffnx {OSPF Command} {no area @var{a.b.c.d} import-list NAME} {}
@deffnx {OSPF Command} {no area <0-4294967295> import-list NAME} {}
Same as export-list, but it applies to paths announced into specified area as
Type-3 summary-LSAs.
@end deffn
@deffn {OSPF Command} {area @var{a.b.c.d} filter-list prefix NAME in} {}
@deffnx {OSPF Command} {area @var{a.b.c.d} filter-list prefix NAME out} {}

@deffnx {OSPF Command} {no area <0-4294967295> filter-list prefix NAME out} {}
Filtering Type-3 summary-LSAs to/from area using prefix lists. This command

Simple text password authentication is insecure and deprecated in favour of
MD5 HMAC authentication (@pxref{ip ospf authentication message-digest}).

Note that OSPF MD5 authentication requires that time never go backwards
(correct time is NOT important, only that it never goes backwards), even
across resets, if ospfd is to be able to promptly reestabish adjacencies
with its neighbours after restarts/reboots. The host should have system
time be set at boot from an external or non-volatile source (eg battery backed clock, NTP,

@file{pimd.conf}. When invocation @command{pimd} searches directory
@value{INSTALL_PREFIX_ETC}. If @file{pimd.conf} is not there
then next search current directory.
@command{pimd} requires zebra for proper operation. Additionally
@command{pimd} depends on routing properly setup and working
in the network that it is working on.

@node PIM Configuration
@deffn Command {ip pim rp A.B.C.D A.B.C.D/M} {}
In order to use pim, it is necessary to configure a RP for join
messages to be sent to. Currently the only methodology to
do this is via static rp commands. All routers in the
pim network must agree on these values. The first ip address
is the RP's address and the second value is the matching
prefix of group ranges covered. This command is vrf aware,
to configure for a vrf, enter the vrf submode.
@end deffn
@deffn Command {ip pim spt-switchover infinity-and-beyond} {}
On the last hop router if it is desired to not switch over
to the SPT tree. Configure this command. This command is
vrf aware, to configure for a vrf, enter the vrf submode.
#end deffn
@deffn Comand {ip pim ecmp} {}
If pim has the a choice of ECMP nexthops for a particular
RPF, pim will cause S,G flows to be spread out amongst
the nexthops. If this command is not specified then
the first nexthop found will be used. This command
is vrf aware, to configure for a vrf, enter the vrf submode.
@end deffn
@deffn Command {ip pim ecmp rebalance} {}
If pim is using ECMP and an interface goes down, cause
pim to rebalance all S,G flows aross the remaining
nexthops. If this command is not configured pim only
modifies those S,G flows that were using the interface
that went down. This command is vrf aware, to configure
for a vrf, enter the vrf submode.
@end deffn
@deffn Command {ip pim join-prune-interval (60-600)} {}
Modify the join/prune interval that pim uses to the
new value. Time is specified in seconds. This command
is vrf aware, to configure for a vrf, enter the vrf submode.
@end deffn
@deffn Command {ip pim keep-alive-timer (31-60000)} {}
Modify the time out value for a S,G flow from 31-60000
seconds. 31 seconds is choosen for a lower bound
because some hardware platforms cannot see data flowing
in better than 30 second chunks. This comand is vrf
aware, to configure for a vrf, enter the vrf submode.
@end deffn
@deffn Command {ip pim packets (1-100)} {}
When processing packets from a neighbor process the
number of packets incoming at one time before moving
on to the next task. The default value is 3 packets.
This command is only useful at scale when you can
possibly have a large number of pim control packets
flowing. This command is vrf aware, to configure for
a vrf, enter the vrf submode.
@end deffn
@deffn Command {ip pim register-suppress-time (5-60000)} {}
Modify the time that pim will register suppress a FHR
will send register notifications to the kernel. This command
is vrf aware, to configure for a vrf, enter the vrf submode.
@end deffn
@deffn Command {ip pim send-v6-secondary} {}
When sending pim hello packets tell pim to send
any v6 secondary addresses on the interface. This
information is used to allow pim to use v6 nexthops
in it's decision for RPF lookup. This command
is vrf aware, to configure for a vrf, enter the vrf submode.
@end deffn
@deffn Command {ip pim ssm prefix-list WORD} {}
Specify a range of group addresses via a prefix-list
that forces pim to never do SM over. This command
is vrf aware, to configure for a vrf, enter the vrf submode.
@end deffn
@deffn Command {ip multicast rpf-lookup-mode WORD} {}
Modify how PIM does RPF lookups in the zebra routing table.
You can use these choices:
@table @lookup_modes
@item longer-prefix
Lookup the RPF in both tables using the longer prefix as a match
@item lower-distance
Lookup the RPF in both tables using the lower distance as a match
@item mrib-only
Lookup in the Multicast RIB only
@item mrib-then-urib
Lookup in the Multicast RIB then the Unicast Rib, returning first found.
This is the default value for lookup if this command is not entered
@item urib-only
Lookup in the Unicast Rib only.
@end table
@end deffn
@node PIM Interface Configuration
@section PIM Interface Configuration
PIM interface commands allow you to configure an
interface as either a Receiver or a interface
that you would like to form pim neighbors on. If the
interface is in a vrf, enter the interface command with
the vrf keyword at the end.
@deffn {PIM Interface Command] {ip pim bfd} {}
Turns on BFD support for PIM for this interface.
@end deffn
@deffn {PIM Interface Command} {ip pim drpriority (1-4294967295)} {}
Set the DR Priority for the interface. This command is useful
to allow the user to influence what node becomes the DR for a
lan segment.
@end deffn

Set the pim hello and hold interval for a interface.
@end deffn
@deffn {PIM Interface Command} {ip pim sm} {}
Tell pim that we would like to use this interface to form
pim neighbors over. Please note we will *not* accept
igmp reports over this interface with this command.
@end deffn
@deffn {PIM Interface Command} {ip igmp} {}
Tell pim to receive IGMP reports and Query on this
interface. The default version is v3. This command
is useful on the LHR.
@end deffn
@deffn {PIM Interface Command} {ip igmp query-interval (1-1800)} {}
Set the IGMP query interval that PIM will use.
@end deffn
@deffn {PIM Interface Command} {ip igmp query-max-response-time (10-250)} {}
Set the IGMP query response timeout value. If an report is not returned
in the specified time we will assume the S,G or *,G has timed out.
@end deffn
@deffn {PIM Interface Command} {ip igmp version (2-3)} {}
Set the IGMP version used on this interface. The default value
is 3.
@end deffn
@deffn {PIM Interface Command} {ip multicat boundary oil WORD} {}
Set a pim multicast boundary, based upon the WORD prefix-list. If
a pim join or IGMP report is received on this interface and the Group
is denyed by the prefix-list, PIM will ignore the join or report.
@end deffn
@node PIM Multicast RIB insertion::
@section PIM Multicast RIB insertion::
In order to influence Multicast RPF lookup, it is possible to insert
into zebra routes for the Multicast RIB. These routes are only
used for RPF lookup and will not be used by zebra for insertion
into the kernel *or* for normal rib processing. As such it is
possible to create weird states with these commands. Use with
caution. Most of the time this will not be necessary.
@deffn {PIM Multicast RIB insertion} {ip mroute A.B.C.D/M A.B.C.D (1-255)} {}
Insert into the Multicast Rib Route A.B.C.D/M with specified nexthop. The distance can be specified as well if desired.
@end deffn

@end deffn
@node Show PIM Information::
@section Show PIM Information
All PIM show commands are vrf aware and typically allow you to insert
a specified vrf command if information is desired about a specific vrf.
If no vrf is specified then the default vrf is assumed. Finally
the special keyword 'all' allows you to look at all vrfs for the command.
Naming a vrf 'all' will cause great confusion.

@node PIM Debug Commands
@section PIM Debug Commands
The debugging subsystem for PIM behaves in accordance with how FRR handles debugging. You can specify debugging at the enable cli mode as well as the configure cli mode. If you specify debug commands in the configuration cli mode, the debug commands can be persistent across restarts of the FRR pimd if the config was written out.
@deffn {PIM Debug Commands} {debug pim events}
This turns on debugging for PIM system events. Especially timers.
@end deffn
@deffn {PIM Debug Commands} {debug pim nht}
This turns on debugging for PIM nexthop tracking. It will display information about RPF lookups and information about when a nexthop changes.
@end deffn
@deffn {PIM Debug Commands} {debug pim packet-dump}
This turns on an extraordinary amount of data. Each pim packet sent and received is dumped for debugging purposes. This should be considered a developer only command
@end deffn
@deffn {PIM Debug Commands} {debug pim packets}

@node Route Map
@chapter Route Map
Route maps provide a means to both filter and/or apply actions to
route, hence allowing policy to be applied to routes.
@menu
* Route Map Command::
* Route Map Match Command::
* Route Map Set Command::
* Route Map Call Command::
* Route Map Exit Action Command::
* Route Map Examples::
@end menu
Route-maps are an ordered list of route-map entries. Each entry may
specify up to four distincts sets of clauses:
@table @samp
@item Matching Policy
This specifies the policy implied if the @samp{Matching Conditions} are
met or not met, and which actions of the route-map are to be taken, if
any. The two possibilities are:
@itemize @minus
@item
@samp{permit}: If the entry matches, then carry out the @samp{Set
Actions}. Then finish processing the route-map, permitting the route,
unless an @samp{Exit Action} indicates otherwise.
@item
@samp{deny}: If the entry matches, then finish processing the route-map and
deny the route (return @samp{deny}).
@end itemize
The @samp{Matching Policy} is specified as part of the command which
defines the ordered entry in the route-map. See below.
@item Matching Conditions
A route-map entry may, optionally, specify one or more conditions which
must be matched if the entry is to be considered further, as governed
by the Match Policy. If a route-map entry does not explicitely specify
any matching conditions, then it always matches.
@item Set Actions
A route-map entry may, optionally, specify one or more @samp{Set
Actions} to set or modify attributes of the route.
@item Call Action
Call to another route-map, after any @samp{Set Actions} have been
carried out. If the route-map called returns @samp{deny} then
processing of the route-map finishes and the route is denied,
regardless of the @samp{Matching Policy} or the @samp{Exit Policy}. If
the called route-map returns @samp{permit}, then @samp{Matching Policy}
and @samp{Exit Policy} govern further behaviour, as normal.
@item Exit Policy
An entry may, optionally, specify an alternative @samp{Exit Policy} to
take if the entry matched, rather than the normal policy of exiting the
route-map and permitting the route. The two possibilities are:
@itemize @minus
@item
@samp{next}: Continue on with processing of the route-map entries.
@item
@samp{goto N}: Jump ahead to the first route-map entry whose order in
the route-map is >= N. Jumping to a previous entry is not permitted.
@end itemize
@end table
The default action of a route-map, if no entries match, is to deny.
I.e. a route-map essentially has as its last entry an empty @samp{deny}
entry, which matches all routes. To change this behaviour, one must
specify an empty @samp{permit} entry as the last entry in the route-map.
To summarise the above:
@multitable {permit} {action} {No Match}
@headitem @tab Match @tab No Match
@item @emph{Permit} @tab action @tab cont
@item @emph{Deny} @tab deny @tab cont
@end multitable
@table @samp
@item action
@itemize @minus
@item
Apply @emph{set} statements
@item
If @emph{call} is present, call given route-map. If that returns a @samp{deny}, finish
processing and return @samp{deny}.
@item
If @samp{Exit Policy} is @emph{next}, goto next route-map entry
@item
If @samp{Exit Policy} is @emph{goto}, goto first entry whose order in the list
is >= the given order.
@item
Finish processing the route-map and permit the route.
@end itemize
@item deny
@itemize @minus
@item
The route is denied by the route-map (return @samp{deny}).
@end itemize
@item cont
@itemize @minus
@item
goto next route-map entry
@end itemize
@end table

@node Route Map Examples
@section Route Map Examples
A simple example of a route-map:
@example
@group
route-map test permit 10
match ip address 10
set local-preference 200
@end group
@end example
This means that if a route matches ip access-list number 10 it's
local-preference value is set to 200.
See @ref{BGP Configuration Examples} for examples of more sophisticated
useage of route-maps, including of the @samp{call} action.
