Usage
Information
When you enable soft-reconfiguration for a neighbor and you execute the clear ip bgp
soft in command, the update database stored in the router is replayed and updates are re-
evaluated. With this command, the replay and update process is triggered only if route-refresh
request is not negotiated with the peer. If the request is indeed negotiated (after executing the
clear ip bgp soft in command), BGP sends a route-refresh request to the neighbor
and receives all of the peer’s updates.
