| 12.2.3 | Interior IP routing protocols
At the Internet layer of the TCP/IP suite of protocols, a router can use an IP routing protocol to accomplish routing through the implementation of a specific routing algorithm. Examples of IP routing protocols include: RIP -- a distance-vector routing protocol IGRP -- Cisco's distance-vector routing protocol OSPF -- a link-state routing protocol EIGRP -- a balanced hybrid routing protocol The following sections show you how to configure the first two of these protocols.
