“clear ip bgp x.x.x.x in” instructs the router to request a route refresh from the specified neighbor. Duplicate routes are then ignored. This is used instead of an older method called ‘soft-reconfiguration inbound’ where the local router would store an unmodified list of the BGP neighbor’s advertised routes in memory and could then clear and reapply inbound routing policy based on the cached route list.
