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 replays 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 negotiated (after execution of clear ip bgp soft in), BGP sends a
route-refresh request to the neighbor and receives all of the peer’s updates.
