If set to 'true', the best route will be advertised to peers, whether or not the route has been added to the forwarding table by the AFM. If set to 'false', then BGP will only advertise a route to peers if the route has been installed in the forwarding table, or if the route has been redistributed by the AFM from another routing protocol instance. It is the responsibility of the AFM to determine whether to only redistribute active routes to BGP. This option requires an AFM to be present, and so bgpRmAfiSafiAdvertiseInactive may only be set to 'false' if bgpRmAfiSafiAfmRequired is set to 'true'. In addition, this option requires that an AFM be configured to inform BGP whenever a route from BGP is successfully installed in the forwarding table, or is removed from the forwarding table. This is achieved by configuring an AFM to redistribute routes from this instance of BGP back to this instance of BGP. Not all AFMs support this redistribution of routes. For such address families, an attempt to set bgpRmAfiSafiAdvertiseInactive to 'false' will be rejected. This field can only be modified while RM is admin down.
