    Hi

    Can anyone tell me why you dont see VPNV4 neighbors in MPLS in this task ?

    I can see routes learnt etc but I dont see any neighbor details below

    RSRack1R4#show bgp vpnv4 unicast vrf VPN_A neighbors

    RSRack1R4#

    Why s this Blank ??

    I knwo i have establiashed a neighbor relationshipas I can asee the routes learnt as per below ?

     

    RSRack1R4#show bgp vpnv4 unicast all

    Not 100% sure what you mean but...

    assuming 200.200.6.1 is your tunnel endpoint at R6? The command you used to show the neighbors will only show BGP peers you have a session with via the VPN_A vrf (rather than showing bgp peers who are passing routes with a route-target or rd of VPN_A). The command will show the BB1 and BB3 routers if run on R4 and R6, but you have to have established the peering via the ADDRESS-FAMILY IPV4 VRF VPN_A bit first. All is (kinda) explained in the solution but let me know if it still doesn't make sense.

    I hereby reserve the right to be wrong most of the time.
