BGP - Advertise Inactive

By default, BGP readvertises only active routes. This feature introduces support to advertise through BGP the best route learned by BGP even if it was not selected to be an active route. By default, BGP advertises BGP routes that are installed or active. The routes are selected based on the BGP path selection rules. This feature allows nonactive BGP routes to be advertised to the peers. The router also provides support for configuring a BGP export policy that matches the state of an advertised route. You can match either active or inactive routes. If the routing table has two BGP routes where one is active and the other is inactive, the advertise-inactive statement configuration does not advertise the inactive BGP prefix. This statement does not advertise an inactive BGP route in the presence of another active BGP route. However, if the active route is a static route, the advertise-inactive statement advertises the inactive BGP route.
