â—† Use this command to clear peering sessions when changes are made to any
BGP access lists, weights, or route-maps.
â—† Route refresh (RFC 2918) allows a router to reset inbound routing tables
dynamically by exchanging route refresh requests with peers. Route refresh
relies on the dynamic exchange of information with supporting peers. It is
advertised through BGP capability negotiation, and all BGP routers must
support this capability.
Example
This example assumes that soft re-configuration has been set on the neighboring
router.
Console(config-router)#clear ip bgp 192.168.0.254 soft in
Console(config-router)#
clear ip bgp
