Monitoring MPLS Next Hops

Purpose

Display MPLS next hops and any available next-hop statistics.

Next hops can be pointed to by MPLS forwarding entries on an LSR, IP or IPv6 routes on an LER, and VPLS bridge groups.

Action

To display MPLS next hops:

host1:vr2#show mpls next-hop
MPLS next-hop: index 1, lookup on inner header/label
   Statistics are not collected for MPLS switch-context next-hops

MPLS next-hop: index 2, lookup in router pe1
   Statistics are not collected for MPLS switch-context next-hops

MPLS next-hop: index 22, ECMP next-hop, leg count 2
   MPLS next-hop: index 20, label 36 on FastEthernet1/1.120, neighbor 10.120.120.1
   MPLS next-hop: index 21, label 36 on ATM2/1.20, neighbor 10.20.20.1
   Statistics are not collected for MPLS ECMP next-hops

MPLS next-hop: index 24, label 17, resolved by MPLS nextHop index 10
   MPLS next-hop: index 10, resolved by MPLS nextHop index 14, peer address 10.1.1.1
      MPLS next-hop: index 14, ECMP next-hop, leg count 2
         MPLS next-hop: index 12, label 32 on FastEthernet1/1.120, neighbor 10.120.120.1
         MPLS next-hop: index 13, label 32 on ATM2/1.20, neighbor 10.20.20.1
   Sent:
     0 packets
     0 bytes
     0 errors
     0 discards

MPLS next-hop: index 25, label 18, resolved by MPLS nextHop index 10
   MPLS next-hop: index 10, resolved by MPLS nextHop index 14, peer address 10.1.1.1
      MPLS next-hop: index 14, ECMP next-hop, leg count 2
         MPLS next-hop: index 12, label 32 on FastEthernet1/1.120, neighbor 10.120.120.1
         MPLS next-hop: index 13, label 32 on ATM2/1.20, neighbor 10.20.20.1
   Sent:
     0 packets
     0 bytes
     0 errors
     0 discards

When one MPLS next-hop points to another MPLS next hop, the second next hop is displayed indented to the first one.

Meaning

Table 49 lists the show mpls next-hop command output fields.
