Intradomain Routing

The initial group of routing protocols comprises intradomain routing protocols, also called interior gateway protocols or IGPs. These protocols are called intradomain because they facilitate information exchange within the same domain or network. Routers use these protocols to share information about reachable destinations within the domain. Intradomain routing protocols include the Routing Information Protocol (RIP), a distance vector protocol, and the Open Shortest Path First (OSPF) that uses link-state routing.

In this section, we briefly describe the key features of the two main intradomain unicast routing protocols: RIP and OSPF.
