Interior gateway routing protocol (
IGRP) is a proprietary
distance-vector routing protocol invented by
Cisco, used by
routers to exchange
routing data within an
autonomous system. IGRP was created to overcome the limitations of
RIP when used within large networks. IGRP's metrics include bandwidth, load, delay, and relability. The maximum hop count of IGRP-routed packets is 255.
EIGRP it's successor, is a hybrid routing protocol, combining link-state and distance-vector.
