The Router Discovery Protocol is an IETF standard protocol used to inform hosts of the existence of routers, rather than using hosts wiretap routing protocols such as RIP. It is used in place of or in addition to statically-configured default routes in hosts.

Digital implements only the server portion of the Router Discovery Protocol.
