Interior Gateway Routing Protocol (2)
IGRP Characteristics
- IGRP is a distance-vector interior gateway protocol (call at regular intervals only to neighboring routes for updates of routing tables)
- metric is a weighted combination of inter-network delay, bandwidth, reliability and load; IGRP provide wide ranges for its metrics; metric components are combined in a user definable algorithm
- multi-path routing allowed (single stream of traffic in round-robin fashion over more than one line)
