Configuring 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.
host1(config-router)# address-family l2vpn signaling
4.
Activate the neighbors with which routes of the L2VPN address family are exchanged
for this PE-to-PE BGP session. Use the
bgp dampening command and BGP neighbor
commands to configure additional address family parameters for the session. No
other commands are supported in this address family.
host1(config-router-af)# neighbor 10.2.2.2 activate
host1(config-router-af)# neighbor 10.2.2.2 next-hop-self
5.
Exit the address family.
host1(config-router-af)# exit-address-family
6.
Create the VPWS address family to configure the router to exchange layer 2 NLRI
for each VPWS instance configured on the router.
You must issue the address-family vpws command separately for each VPWS
instance configured on the router.
host1(config-router)# address-family vpws l2vpnA
host1(config-router)# address-family vpws l2vpnB
