Hello, I am practicing some multi-vrf CE configurations and the guide I am using shows that you need "mpls bgp forwarding" command on the CE-PE sub-interfaces. I have got this to work without that command or BGP send-label on the PE. Are these commands not required? It is really just looking like a B2B VRF configuration. Without these commands, am I at risk of losing some functionality? I can't see any thing wrong, and I do have connectivity from CE to CE.
Reference: http://www.cisco.com/en/US/docs/ios/12_2sb/12_2sba/feature/guide/vrflite.html My CE config merely looks like this (addresses have been changed from the document). ip vrf VPNA rd 800:1 route-target export 800:1 route-target import 800:1 ! ip vrf VPNB rd 800:2 route-target export 800:2 route-target import 800:2 ! interface Loopback100 ip vrf forwarding VPNA ip address 100.1.1.1 255.255.255.255 ! interface Loopback200 ip vrf forwarding VPNB ip address 200.1.1.1 255.255.255.255 ! interface FastEthernet0/0 no ip address duplex auto speed auto ! interface FastEthernet0/0.100 encapsulation dot1Q 100 ip vrf forwarding VPNA ip address 192.168.100.2 255.255.255.0 ! interface FastEthernet0/0.200 encapsulation dot1Q 200 ip vrf forwarding VPNB ip address 192.168.200.2 255.255.255.0 ! router bgp 65000 bgp router-id 100.1.1.1 no bgp default ipv4-unicast bgp log-neighbor-changes ! address-family ipv4 vrf VPNB neighbor 192.168.200.1 remote-as 100 neighbor 192.168.200.1 activate no synchronization network 200.1.1.1 mask 255.255.255.255 exit-address-family ! address-family ipv4 vrf VPNA neighbor 192.168.100.1 remote-as 100 neighbor 192.168.100.1 activate no synchronization network 100.1.1.1 mask 255.255.255.255 exit-address-family !
