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.
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
