From Introduction to Network Security Lectures at Xi'an Jaotong University -- Sept 1998. by Roman Markowski


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)
