* peer pointer (otherwise, if they have the same peer pointer, each
* route will be considered an implicit waithdraw of the previous
* route injected from that peer, and the new route will replace

## Topology
The goal of this test is to verify that the all the basic functionality
of ldpd is working as expected, be it running on Linux or OpenBSD. In
addition to that, more advanced features are also tested, like LDP
sessions over IPv6, MD5 authentication and pseudowire signaling.
In the topology below there are 3 PE routers, 3 CE routers and one P
router (not attached to any consumer site).
All routers have IPv4 addresses and OSPF is used as the IGP. The
three routers from the bottom of the picture, P, PE2 and PE3, are also
configured for IPv6 (dual-stack) and static IPv6 routes are used to
provide connectivity among them.
The three CEs share the same VPLS membership. LDP is used to set up the
LSPs among the PEs and to signal the pseudowires. MD5 authentication is
used to protect all LDP sessions.

```
## Configuration
#### Linux
1 - Enable IPv4/v6 forwarding:
```
# sysctl -w net.ipv4.ip_forward=1
# sysctl -w net.ipv6.conf.all.forwarding=1
```
2 - Enable MPLS forwarding:
```
# modprobe mpls-router
# modprobe mpls-iptunnel
# echo 100000 > /proc/sys/net/mpls/platform_labels
# echo 1 > /proc/sys/net/mpls/conf/eth1/input
# echo 1 > /proc/sys/net/mpls/conf/eth2/input
```
3 - Set up the interfaces:
```
# ip link add name lo1 type dummy
# ip link set dev lo1 up
# ip addr add 4.4.4.4/32 dev lo1
# ip -6 addr add 4:4:4::4/128 dev lo1
# ip link set dev eth1 up
# ip addr add 10.0.4.4/24 dev eth1
# ip -6 addr add 2001:db8:4::4/64 dev eth1
# ip link set dev eth2 up
# ip addr add 10.0.3.4/24 dev eth2
# ip -6 addr add 2001:db8:3::4/64 dev eth2
```
4 - Set up the bridge and pseudowire interfaces:
```
# ip link add type bridge
# ip link set dev bridge0 up
# ip link set dev eth0 up
# ip link set dev eth0 master bridge0
# ip link add name mpw0 type dummy
# ip link set dev mpw0 up
# ip link set dev mpw0 master bridge0
# ip link add name mpw1 type dummy
# ip link set dev mpw1 up
# ip link set dev mpw1 master bridge0
```
> NOTE: MPLS support in the Linux kernel is very recent and it still
doesn't support pseudowire interfaces. We are using here dummy interfaces
just to show how the VPLS configuration should look like in the future.
5 - Add static IPv6 routes for the remote loopbacks:
```
# ip -6 route add 2:2:2::2/128 via 2001:db8:3::2
# ip -6 route add 3:3:3::3/128 via 2001:db8:4::3
```
6 - Edit /etc/quagga/ospfd.conf:
```
router ospf
network 4.4.4.4/32 area 0.0.0.0
network 10.0.3.4/24 area 0.0.0.0
network 10.0.4.4/24 area 0.0.0.0
!
```

```
> NOTE: We have to disable ttl-security under the ipv6 address-family
in order to interoperate with the IOS-XR router. GTSM is mandatory for
LDPv6 but the IOS-XR implementation is not RFC compliant in this regard.
8 - Run zebra, ospfd and ldpd.
#### OpenBSD
1 - Enable IPv4/v6 forwarding:
```
# sysctl net.inet.ip.forwarding=1
# sysctl net.inet6.ip6.forwarding=1
```
2 - Enable MPLS forwarding:
```
# ifconfig em2 10.0.2.3/24 mpls
# ifconfig em3 10.0.4.3/24 mpls
```
3 - Set up the interfaces:
```
# ifconfig lo1 alias 3.3.3.3 netmask 255.255.255.255
# ifconfig lo1 inet6 3:3:3::3/128
# ifconfig em2 inet6 2001:db8:2::3/64
# ifconfig em3 inet6 2001:db8:4::3/64
```
4 - Set up the bridge and pseudowire interfaces:
```
# ifconfig bridge0 create
# ifconfig bridge0 up
# ifconfig em1 up
# ifconfig bridge0 add em1
# ifconfig mpw0 create
# ifconfig mpw0 up
# ifconfig bridge0 add mpw0
# ifconfig mpw1 create
# ifconfig mpw1 up
# ifconfig bridge0 add mpw1
```
5 - Add static IPv6 routes for the remote loopbacks:
```
# route -n add 4:4:4::4/128 2001:db8:4::4
# route -n add 2:2:2::2/128 2001:db8:2::2
```

## Verification - Control Plane
Using the CLI on the Linux box, the goal is to ensure that everything
is working as expected.
First, verify that all the required adjacencies and neighborships sessions
were established:
```
linux# show mpls ldp discovery
Local LDP Identifier: 4.4.4.4:0
Discovery Sources:
Interfaces:
eth1: xmit/recv
LDP Id: 3.3.3.3:0, Transport address: 3.3.3.3
Hold time: 15 sec
LDP Id: 3.3.3.3:0, Transport address: 3:3:3::3
Hold time: 15 sec
eth2: xmit/recv
LDP Id: 2.2.2.2:0, Transport address: 2.2.2.2
Hold time: 15 sec
LDP Id: 2.2.2.2:0, Transport address: 2:2:2::2
Hold time: 15 sec
Targeted Hellos:
4.4.4.4 -> 1.1.1.1: xmit/recv
LDP Id: 1.1.1.1:0, Transport address: 1.1.1.1
Hold time: 45 sec
4:4:4::4 -> 3:3:3::3: xmit/recv
LDP Id: 3.3.3.3:0, Transport address: 3:3:3::3
Hold time: 45 sec
linux# show mpls ldp neighbor
Peer LDP Identifier: 1.1.1.1:0
TCP connection: 4.4.4.4:40921 - 1.1.1.1:646
Session Holdtime: 180 sec
State: OPERATIONAL; Downstream-Unsolicited
Up time: 00:06:02
LDP Discovery Sources:
IPv4:
Targeted Hello: 1.1.1.1
Peer LDP Identifier: 2.2.2.2:0
TCP connection: 4:4:4::4:52286 - 2:2:2::2:646
Session Holdtime: 180 sec
State: OPERATIONAL; Downstream-Unsolicited
Up time: 00:06:02
LDP Discovery Sources:
IPv4:
Interface: eth2
IPv6:
Interface: eth2
Peer LDP Identifier: 3.3.3.3:0
TCP connection: 4:4:4::4:60575 - 3:3:3::3:646
Session Holdtime: 180 sec
State: OPERATIONAL; Downstream-Unsolicited
Up time: 00:05:57
LDP Discovery Sources:
IPv4:
Interface: eth1
IPv6:
Targeted Hello: 3:3:3::3
Interface: eth1
```
Note that the neighborships with the P and PE2 routers were established
over IPv6, since this is the default behavior for dual-stack LSRs, as
specified in RFC 7552. If desired, the **dual-stack transport-connection
prefer ipv4** command can be used to establish these sessions over IPv4
(the command should be applied an all routers).
Now, verify that there's a remote label for each PE address:
```
linux# show mpls ldp binding

```
Check if the pseudowires are up:
```
linux# show l2vpn atom vc
Interface Peer ID VC ID Name Status
--------- --------------- ---------- ---------------- ----------
mpw1 3.3.3.3 100 ENG UP
mpw0 1.1.1.1 100 ENG UP
```
Check the label bindings of the pseudowires:
```
linux# show l2vpn atom binding
Destination Address: 1.1.1.1, VC ID: 100
Local Label: 25
Cbit: 1, VC Type: Ethernet, GroupID: 0
MTU: 1500

MTU: 1500
Remote Label: 26
Cbit: 1, VC Type: Ethernet, GroupID: 0

```
## Verification - Data Plane
Verify that all the exchanged label mappings were installed in zebra:
```

Verify that all the exchanged label mappings were installed in the kernel:
```
$ ip -M ro

24 via inet 10.0.3.2 dev eth2 proto zebra
25 via inet 10.0.3.2 dev eth2 proto zebra
$
$ ip route | grep mpls

3.3.3.3 encap mpls 24001 via 10.0.3.2 dev eth2 proto zebra metric 20
```
Now ping PE1's loopback using lo1's address as a source address:
```
$ ping -c 5 -I 4.4.4.4 1.1.1.1

Verify that the ICMP echo request packets are leaving with the MPLS
label advertised by the P router. Also, verify that the ICMP echo reply
packets are arriving with an explicit-null MPLS label:
```

.SH DESCRIPTION
.B ldpd
is a component that works with the
.B Quagga
routing engine.
.SH OPTIONS
Options available for the
.B ldpd
command:
.TP
\fB\-d\fR, \fB\-\-daemon\fR
Runs in daemon mode, forking and exiting from tty.
.TP
\fB\-f\fR, \fB\-\-config-file \fR\fIconfig-file\fR
Specifies the config file to use for startup. If not specified this
option will likely default to \fB\fI/usr/local/etc/ldpd.conf\fR.
.TP
\fB\-g\fR, \fB\-\-group \fR\fIgroup\fR
Specify the group to run as. Default is \fIquagga\fR.
.TP
\fB\-h\fR, \fB\-\-help\fR
A brief message.
.TP
\fB\-i\fR, \fB\-\-pid_file \fR\fIpid-file\fR
When ldpd starts its process identifier is written to
\fB\fIpid-file\fR. The init system uses the recorded PID to stop or
restart ldpd. The likely default is \fB\fI/var/run/ldpd.pid\fR.
.TP
\fB\-P\fR, \fB\-\-vty_port \fR\fIport-number\fR
Specify the port that the ldpd VTY will listen on. This defaults to
2612, as specified in \fB\fI/etc/services\fR.
.TP
\fB\-A\fR, \fB\-\-vty_addr \fR\fIvty-address\fR
Specify the address that the ldpd VTY will listen on. Default is all
interfaces.
.TP
\fB\-u\fR, \fB\-\-user \fR\fIuser\fR
Specify the user to run as. Default is \fIquagga\fR.
.TP
\fB\-v\fR, \fB\-\-version\fR
Print the version and exit.
.SH FILES
.TP
.BI /usr/local/sbin/ldpd
The default location of the
.B ldpd
binary.
.TP
.BI /usr/local/etc/ldpd.conf
The default location of the
.B ldpd
config file.
.TP
.BI $(PWD)/ldpd.log
If the
.B ldpd
process is config'd to output logs to a file, then you will find this
file in the directory where you started \fBldpd\fR.
.SH WARNING
This man page is intended to be a quick reference for command line
options. The definitive document is the Info file \fBQuagga\fR.
.SH DIAGNOSTICS
The ldpd process may log to standard output, to a VTY, to a log
file, or through syslog to the system logs. \fBldpd\fR supports many
debugging options, see the Info file, or the source for details.
