IGRP
(Interior Gateway Routing Protocol)
Interior Gateway Routing Protocol (IGRP) is a distance-vector routing protocol used to determine the best path for data packets within an autonomous system (AS). IGRP was developed by Cisco and is a predecessor to EIGRP (Enhanced IGRP).
IGRP uses metrics like bandwidth, delay, and reliability to calculate optimal routes. While IGRP is largely obsolete, it laid the foundation for modern routing protocols. It is primarily used in legacy Cisco networks and has been replaced by more advanced protocols like OSPF and EIGRP.
