Fix Recommendation

Configure the correct RD for each VRF.

RP/0/0/CPU0:R3(config)#router bgp nn
RP/0/0/CPU0:R3(config-bgp)#vrf COI1
RP/0/0/CPU0:R3(config-bgp-vrf)#rd 13:13

Review the design plan for MPLS/L3VPN to determine what RD have been assigned for each VRF. Review the router configuration and verify that the correct RD is configured for each VRF. In the example below, route distinguisher 13:13 has been configured for COI1.

router bgp nn
address-family ipv4 unicast
!
address-family vpnv4 unicast
!



!
vrf COI1
rd 13:13
address-family ipv4 unicast
redistribute ospf 1
