Implementing and Monitoring RIB

Verifying Networking and Routing Problems

Perform this task to verify the operation of routes between nodes.
SUMMARY STEPS
1. show route [ vrf { vrf-name | all }] [ afi-all | ipv4 | ipv6 ] [ unicast | multicast | safi-all ] [ protocol
[ instance ] | ip-address mask ] [ standby ] [ detail ]
2. show route [ vrf { vrf-name | all }] [ afi-all | ipv4 | ipv6 ] [ unicast | multicast | safi-all ] backup
[ ip-address ] [ standby ]
3. show route [ vrf { vrf-name | all }] [ ipv4 | ipv6 ] [ unicast | multicast | safi-all ] best-local
ip-address [ standby ]
4. show route [ vrf { vrf-name | all }] [ afi-all | ipv4 | ipv6 ] [ unicast | multicast | safi-all ]
connected [ standby ]
5. show route [ vrf { vrf-name | all }] [ afi-all | ipv4 | ipv6 ] [ unicast | multicast | safi-all ] local
[ interface ] [ standby ]
6. show route [ vrf { vrf-name | all }] [ ipv4 | ipv6 ] [ unicast | multicast | safi-all ] longer-prefixes
{ ip-address mask | ip-address / prefix-length } [ standby ]
7. show route [ vrf { vrf-name | all }] [ ipv4 | ipv6 ] [ unicast | multicast | safi-all ] next-hop
ip-address [ standby ]
DETAILED STEPS
Command or Action
Step 1
show route [ vrf { vrf-name | all }] [ afi-all | ipv4 | ipv6 ] [ unicast |
multicast | safi-all ] [ protocol [ instance ] | ip-address mask ] [ standby
] [ detail ]
Example:
RP/0/RSP0/CPU0:router# show route ipv4 unicast 192.168.1.11/8
Step 2 show route [ vrf { vrf-name | all }] [ afi-all | ipv4 | ipv6 ] [ unicast |
multicast | safi-all ] backup [ ip-address ] [ standby ]
Example:
RP/0/RSP0/CPU0:router# show route ipv4 unicast backup
192.168.1.11/8
Step 3 show route [ vrf { vrf-name | all }] [ ipv4 | ipv6 ] [ unicast | multicast
| safi-all ] best-local ip-address [ standby ]
Example:
RP/0/RSP0/CPU0:router# show route ipv4 unicast best-local
192.168.1.11/8
