Interior Gateway Routing Protocol (IGRP) is a distance vector protocol suitable for medium and large-sized networks. IGRP uses a composite metric that is calculated by a combination of delay, bandwidth, reliability, load, and Maximum Transmission Unit (MTU).

This chapter discusses various problems, their effective isolation, and different methods to resolve these problems in IGRP routing environments.
