What is DUAL?

By

The diffusing update algorithm (DUAL) is the algorithm used by EIGRP routing protocol to make sure that a given route is recalculated globally whenever it might cause a routing loop. It is guarantees loop-free and backup paths throughout the routing domain. EIGRP store all available backup routes using diffusing update algorithm and then adapt the… Read more

Enhanced Interior Gateway Routing Protocol (EIGRP) was introduced as a distance-vector routing protocol in 1992. It was originally designed to work as a Cisco proprietary protocol on Cisco devices only. In 2013, Enhanced Interior Gateway Routing Protocol became a multi-vendor routing protocol. Enhanced Interior Gateway Routing Protocol is an advanced version of IGRP that lets
