3 MP-BGP configuration
Create VRF on ESR1 and ESR3, respectively. Specify RD, rt-export/import in accordance with our scheme.
ESR1(config)# ip vrf Customer1
ESR1(config-vrf)# ip protocols bgp max-routes 1000
ESR1(config-vrf)# rd 65500:100
ESR1(config-vrf)# route-target import 65500:100
ESR1(config-vrf)# route-target export 65500:100
ESR3(config)# ip vrf Customer1
ESR3(config-vrf)# ip protocols bgp max-routes 1000
ESR3(config-vrf)# rd 65500:100
ESR3(config-vrf)# route-target export 65500:100
ESR3(config-vrf)# route-target import 65500:100
ESR3(config-vrf)# exit
Without specifying RD and RT attributes the route information will not get into the VPNv4 table.
