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.
