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 2Meaning
Table 1 lists the show ip bgp next-hops command output fields.
Table 1: 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 |
