Frequently asked questions

EIGRP (Enhanced Interior Gateway Routing Protocol) is a routing protocol developed by Cisco that allows routers to exchange information about network routes and provides dynamic routing capabilities. It is an enhanced version of IGRP (Interior Gateway Routing Protocol) and offers features like fast convergence, partial updates, and neighbor discovery.

EIGRP utilizes the DUAL (Diffusing Update Algorithm) to achieve fast convergence. This algorithm ensures that routing information is updated quickly when network changes occur, minimizing disruption to data flow.

EIGRP scales well to large networks due to its efficient routing algorithm and partial update mechanism. It minimizes bandwidth consumption by sending only necessary updates, reducing network traffic and improving performance.

EIGRP utilizes a loop-free path selection mechanism based on the DUAL algorithm. This algorithm ensures that the paths chosen for routing do not contain loops, preventing network congestion and data loss.
