A technique dynamically configures and verifies routing information of broadcast networks using link state protocols in a computer network. According to the novel technique, a router within the broadcast network receives a link state protocol routing information advertisement from an advertising router, e.g., a designated router or other adjacent neighbor.

In the event the next-hop for the destination is not directly addressable by the router (e.g., no adjacency or reply), the router installs a route to the destination via the designated router. Otherwise, the router installs a route to the destination via the next-hop.
