SUMMARY STEPS
1.
show bgp neighbors
2.
clear bgp { ipv4 { unicast | multicast | all | tunnel } | ipv6 unicast | all { unicast | multicast
| all | tunnel } | vpnv4 unicast | vrf { vrf-name | all } { ipv4 unicast | ipv6 unicast } { * |
ip-address | as as-number | external } soft [ in [ prefix-filter ] | out ]
DETAILED STEPS
PurposeCommand or Action
Verifies that received route refresh capability from the
neighbor is enabled.
show bgp neighbors
Example:
RP/0/RSP0/CPU0:router# show bgp neighbors
Step 1
Soft resets a BGP neighbor.clear bgp { ipv4 { unicast | multicast | all | tunnel }
| ipv6 unicast | all { unicast | multicast | all | tunnel
Step 2
•
The * keyword resets all BGP neighbors.
} | vpnv4 unicast | vrf { vrf-name | all } { ipv4 unicast
| ipv6 unicast } { * | ip-address | as as-number |
external } soft [ in [ prefix-filter ] | out ]
•
The ip-address argument specifies the address of the
neighbor to be reset.
Example:
RP/0/RSP0/CPU0:router# clear bgp ipv4 unicast
10.0.0.1 soft in
•
The as-number argument specifies that all neighbors
that match the autonomous system number be reset.
•
The external keyword specifies that all external
neighbors are reset.
Resetting Neighbors Using BGP Outbound Soft Reset
Perform this task to trigger an outbound soft reset of the specified address families for the specified group or
neighbors. The group is specified by the * , ip-address , as-number , or external keywords and arguments.
Resetting neighbors is useful if you change the outbound policy for the neighbors or any other configuration
that affects the sending or receiving of routing updates.
If an outbound soft reset is triggered, BGP resends all routes for the address family to the given neighbors.
To determine whether the neighbor has advertised the ROUTE_REFRESH capability, use the show bgp
neighbors command.
