Routing Protocol

Definition - 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.

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
