——————————————-------------
- etc/init.d/quagga is modified to support creating separate ospf daemon
process for each instance. Each individual instance is monitored by
watchquagga just like any protocol daemons.(requires initd-mi.patch).
- Vtysh is modified to able to connect to multiple daemons of the same
protocol (supported for OSPF only for now).
- ospfd is modified to remember the Instance-ID that its invoked with. For
the entire life of the process it caters to any command request that
matches that instance-ID (unless its a non instance specific command).
Routes/messages to zebra are tagged with instance-ID.
- zebra route/redistribute mechanisms are modified to work with
[protocol type + instance-id]
- bgpd now has ability to have multiple instance specific redistribution
for a protocol (OSPF only supported/tested for now).
- zlog ability to display instance-id besides the protocol/daemon name.
- Changes in other daemons are to because of the needed integration with
some of the modified APIs/routines. (Didn’t prefer replicating too many
separate instance specific APIs.)
- config/show/debug commands are modified to take instance-id argument
as appropriate.
Guidelines to start using multi-instance ospf
---------------------------------------------
The patch is backward compatible, i.e for any previous way of single ospf
deamon(router ospf <cr>) will continue to work as is, including all the
show commands etc.
To enable multiple instances, do the following:
1. service quagga stop
2. Modify /etc/quagga/daemons to add instance-ids of each desired
instance in the following format:
ospfd=“yes"
ospfd_instances="1,2,3"
assuming you want to enable 3 instances with those instance ids.
3. Create corresponding ospfd config files as ospfd-1.conf, ospfd-2.conf
and ospfd-3.conf.
4. service quagga start/restart
5. Verify that the deamons are started as expected. You should see
ospfd started with -n <instance-id> option.
ps –ef | grep quagga
With that /var/run/quagga/ should have ospfd-<instance-id>.pid and
ospfd-<instance-id>/vty to each instance.
6. vtysh to work with instances as you would with any other deamons.
7. Overall most quagga semantics are the same working with the instance
deamon, like it is for any other daemon.
NOTE:
To safeguard against errors leading to too many processes getting invoked,
a hard limit on number of instance-ids is in place, currently its 5.
Allowed instance-id range is <1-65535>
Once daemons are up, show running from vtysh should show the instance-id
of each daemon as 'router ospf <instance-id>’ (without needing explicit
configuration)
Instance-id can not be changed via vtysh, other router ospf configuration
is allowed as before.

Zebra OSPF daemon for IPv6 network

README for newer code is not yet. General usage should remain
the same. For further usage, see command helps by typing '?'
in vty, and then imagin ! ;p) Previous README contents follows.
Zebra OSPF daemon for IPv6 network
2001/12/20
Zebra OSPF6d is OSPF version 3 daemon which is specified by
"OSPF for IPv6" (RFC 2740).
*** NOTE ***
Zebra ospf6d is in development yet. It may lack some functionalities,
and may have some bugs. Use the latest version from the anoncvs
repository (http://www.zebra.org/cvs.html) !
This file README is like memo yet, so please feel free to ask
<yasu@sfc.wide.ad.jp> by E-mail. Patches will be appriciated.
ospf6d's vty port was default to 2606/tcp.
Use commands below.
VIEW NODE:
show ipv6 ospf6
To see Router-ID, uptime of ospf6d, some statistics.
show ipv6 ospf6 database ...
This command shows LSA database. You can specify
LS-type/LS-ID/Advertising-Router of LSAs. '*' is recognized.
show ipv6 ospf6 interface ...
To see the status of the OSPF interface, and the configuration
like interface costs.
show ipv6 ospf6 neighbor ...
Shows state of neighbors and choosed (Backup) DR on the I/F.
show ipv6 ospf6 route (X::X)
This command shows internal routing table of the ospf6d.
Routes not calculated by OSPFv3 (like connected routes)
are not shown. If Address is specified (X::X), shows the route
that the address matches.
show ipv6 ospf6 route redistribute (X::X)
Shows the routes advertised as AS-External routes by the router
itself. If Address is specified (X::X), shows the route
that the address matches.
CONFIG NODE:
interface NAME
To enter INTERFACE NODE
router ospf6 ...
To enter OSPF6 NODE
INTERFACE NODE:
ipv6 ospf6 cost COST
Sets the interface's output cost. Depends on interface bandwidth by default.
ipv6 ospf6 hello-interval HELLOINTERVAL
Sets the interface's Hello Interval. default 10
ipv6 ospf6 dead-interval DEADINTERVAL
Sets the interface's Router Dead Interval. default 40
ipv6 ospf6 retransmit-interval RETRANSMITINTERVAL
Sets the interface's Rxmt Interval. default 5
ipv6 ospf6 priority PRIORITY
Sets the interface's Router Priority. default 1
ipv6 ospf6 transmit-delay TRANSMITDELAY
Sets the interface's Inf-Trans-Delay. default 1
OSPF6 NODE:
router-id A.B.C.D
Sets the router's Router-ID
interface NAME area AREA
Binds interface to specified Area, and start
sending OSPFv3 packets.
auto-cost reference-bandwidth COST
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.
Sample configuration is in ospf6d.conf.sample.
