    Monitoring BGP Next Hops for VPWS L2VPNS

    Purpose

    Display information about BGP next hops in the L2VPN address family or in the VPWS address family

    Action

    To display BGP next hop information that matches the specified indirect next-hop address (2.2.2.2) in the L2VPN address family:

    host1#show ip bgp l2vpn all next-hops 10.2.2.2
    Indirect next-hop 10.2.2.2
      Resolution in IP route table of VR 
           IP indirect next-hop index 2
           Reachable (metric 3)
           Number of direct next-hops is 1
                  Direct next-hop ATM2/0.10 (10.10.10.2)
      Resolution in IP tunnel-route table of VR 
           MPLS indirect next-hop index 19
           Reachable (metric 3)
           Number of direct next-hops is 1
                  Direct next-hop 0000000c
      Reference count is 2
