Usage
Information
When soft-reconfiguration is enabled for a neighbor and the clear ip bgp soft in is executed, the
update database stored in the router is replayed and updates are reevaluated. 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 (upon execution of clear ip bgp soft in), then BGP sends a
route-refresh request to the neighbor and receives all of the peer’s updates.
