1.4 Routing Protocol
1.4.7 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.
  • Enhanced IGRP-A balanced hybrid routing protocol.
