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.
