Configuring BGP Signaling for VPWS
This section describes one way to configure BGP signaling for VPWS, but does not
provide complete details about configuring BGP and BGP/MPLS VPNs..
Table 102 on page 664 lists the commands used in this section to configure BGP
signaling for VPWS.

To configure BGP signaling for an VPWS L2VPN on the PE router:
1. Enable the BGP routing process on the PE router in the specified local AS.
The AS number identifies the PE router to other BGP routers.
host1(config)#router bgp 738
2. Configure the PE-to-PE BGP session. Use neighbor commands to specify the PE
router peers to which BGP advertises routes and to configure additional BGP
attributes.
host1(config-router)#neighbor 10.2.2.2 remote-as 738
host1(config-router)#neighbor 10.2.2.2 update-source loopback 0
host1(config-router)#neighbor 10.2.2.2 next-hop-self
3. Create the L2VPN address family to configure the router to use BGP signaling to
exchange layer 2 NLRI to peer PE routers for all VPWS instances.
Optionally, you can use the signaling
keyword with the
address-family command when you configure the L2VPN address family to
specify BGP signaling of VPWS reachability information. Currently, you can omit
the signaling
keyword with no adverse effects.
