What Does Routing Protocol Mean?

A routing protocol uses software and routing algorithms to determine optimal network data transfer and communication paths between network nodes. Routing protocols facilitate router communication and overall network topology understanding.


A routing protocol is also known as a routing policy.

Techopedia Explains Routing Protocol

Most Internet Protocol (IP) networks use the following routing protocols:

  • Routing Information Protocol (RIP) and Interior Gateway Routing Protocol (IGRP): These provide interior gateway routing through path or distance vector protocols.
  • Open Shortest Path First (OSPF): This provides interior gateway routing through link-state routing protocols.
  • Border Gateway Protocol (BGP) v4: This provides public Internet routing protocol through exterior gateway routing
