Case Study-Multi-Homed Inter-AS Provider Network

Router(config-router)#no bgp default route-target filter

Using the no form of this command causes all received VPN-IPv4 routes to be accepted by the router. In an Inter-AS environment, accepting VPN-IPv4 routes is the desired behavior for a router configured as an autonomous system border edge router.

Router(config-router)#neighbor ip-address send-label

Enables a router to use BGP to distribute MPLS labels along with the IPv4 routes to a peer router. This command has to be enabled on both the BGP routers peering to each other.
