Chapter 8. Enhanced Interior Gateway Routing Protocol
This chapter discusses the Enhanced Interior Gateway Routing Protocol (Enhanced IGRP), including the following topics:
Fundamentals and operation of Enhanced IGRP This section describes Enhanced IGRP, which is an advanced distance-vector protocol, based on the concept that each router does not need to know all the router/link relationships for the entire network.
The DUAL algorithm This section discusses the Distributed Update Algorithm (DUAL), which is the algorithm used to obtain loop-freedom at every instant throughout a route computation.
How the Enhanced IGRP topology table is built Here, we explain how the topology table contains destinations advertised by neighboring routers. Associated ...
