If the distant gateway resumes sending RIP responses, the associated route is restored. Such gateways can be useful on media that do not support broadcasts or multicasts but otherwise act like classic shared media like Ethernets such as some ATM networks. Gateways marked external are also passive, but are not placed in the ker- nel routing table nor are they included in routing updates. Such entries are only required when both routers may learn of routes to the same destination. Gname is the name or address of the gateway to which RIP responses should be forwarded.
Value is the hop count to the destination host or network.
If no interfaces are allowed to process RIP packets, routed acts purely as a router discovery daemon. When RIPv2 routes are multicast, so that RIPv1 listeners cannot receive them, this feature causes a RIPv1 default route to be broadcast to RIPv1 listeners.
