A request for a complete routing table is being sent, or has been received depending on the contents of the last EZB4045I message. This message is sent during session initialization by NCPROUTE. In addition to foreign routers making this request, application programs can ask a client for its tables by sending a Routing Information Protocol (RIP) request for a route with an address family of 0 and a metric of 16 to a client NCP at the current RouteD port (by default, 520).
