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.
