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.

Cisco ASR 9000 Series Aggregation Services Router Routing Configuration Guide, Release 5.3.x
Resetting Neighbors Using BGP Outbound Soft Reset
Purpose
Verifies that received route refresh capability from the
neighbor is enabled.
Soft resets a BGP neighbor.
• The * keyword resets all BGP neighbors.
• The ip-address argument specifies the address of the
neighbor to be reset.
• 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.
