Configuring ASBRs to Exchange IPv4 Routes and MPLS Labels
This example shows how to configure the autonomous system boundary routers (ASBRs) to exchange IPv4
routes and MPLS labels.
Configuration Example
Router# configure
Router(config)#router bgp 500
Router(config-bgp)#address-family ipv4 unicast
Router(config-bgp-af)#allocate-label all
Router(config-bgp-af)#neighbor 16.1.1.1
Router(config-bgp-nbr)#remote-as 100
Router(config-bgp-nbr)#address-family ipv4 labeled-unicast
Router(config-bgp-nbr-af)#route-policy pass-all in
Router(config-bgp-nbr-af)#route-policy pass-all out
Router(config-bgp-nbr-af)#commit
Running Configuration
router bgp 500
bgp router-id 60.200.11.1
