Usage guidelines
A soft-reset operation enables the router to apply a new route selection policy without tearing down BGP
connections.
To apply a new policy to outbound BGP sessions, execute this command with the export keyword. The
router uses the new policy to filter routing information and sends the routing information that passes the
filtering to the BGP peers.
To apply a new policy to inbound sessions, execute this command with the import keyword. The router
advertises a route-refresh message to the peer and the peer resends its routing information to the router.
After receiving the routing information, the router uses the new policy to filter the routing information.
