Novell Internet Access Server 4.1 routing software supports the Routing Table Maintenance Protocol (RTMP) and the AppleTalk Update-Based Routing Protocol (AURP).
Routers use routing protocols to create and dynamically maintain a database of routing information called the Routing Information Table . This table contains information about all the networks on the AppleTalk internetwork. The router uses this information to forward packets to their destinations by the best possible route.
AppleTalk routing tables contain an entry for every network in the internetwork. AppleTalk learns the network ranges and/or network numbers of its directly connected interfaces through configuration of the seed router. If the router is configured as a non-seed router, the router listens to seed routers on the network and learns addressing information about its directly connected interfaces. An AppleTalk router learns about networks not directly connected to it through the exchange of routing information with each of its neighbors.
A router's neighbor is a router that has at least one interface on the same network. By learning its neighbor's routing information, the router learns about the entire internetwork.
