Monitoring BGP Next Hops for VPLS

Purpose

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

Action

To display 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 2.2.2.2
Indirect next-hop 2.2.2.2
  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

Meaning

Table 129 lists the show ip bgp next-hops command output fields.

Table 129: show ip bgp next-hops Output Fields

Field Name

Field Description

Indirect next-hop

BGP next-hop attribute received in the BGP update message

Resolution

Describes where the indirect next hop is resolved (the IP routing table, the IP tunnel routing table, or both) and whether this is in a VR or VRF

IP indirect next-hop index

Index number of the IP indirect next hop that corresponds to the BGP indirect next hop and its resolution

MPLS indirect next-hop index

Index number of the MPLS indirect next hop that corresponds to the BGP indirect next hop and its resolution

Reachable

Indicates whether or not the indirect next hop is reachable. For more information about the reachability rules that apply for various route types, see the command description for show ip bgp next-hops

metric

Metric number of the BGP indirect next hop

Number of direct next-hops

Number of the equal-cost legs of direct next hops to which this indirect next hop resolves

Direct next-hop

MPLS next-hop index that resolves the MPLS indirect next hop

Reference count

Number of label mappings of BGP routes that use this next hop
