EIGRP EIGRP is a Cisco-proprietary routing protocol for TCP/IP. It's actually based on Cisco's proprietary IGRP routing protocol, with many enhancements built into it. Because it has its roots in IGRP, the configuration is similar to IGRP; however, it has many link state characteristics that were added to it to allow EIGRP to scale to enterprise network sizes. To know these characteristics read our previous article. In this article I will demonstrate an example of EIGRP Routing configurations. We will use four different series router so you can get familiar with all different platform covered in CCNA exam Routing Information Protocol (RIP)

EIGRP

EIGRP is a Cisco-proprietary routing protocol for TCP/IP. It's actually based on

Cisco's proprietary IGRP routing protocol, with many enhancements built into it.

Because it has its roots in IGRP, the configuration is similar to IGRP; however, it has

many link state characteristics that were added to it to allow EIGRP to scale to

enterprise network sizes. To know these characteristics read our previous article.

In this article I will demonstrate an example of EIGRP Routing configurations. We

will use four different series router so you can get familiar with all different platform

covered in CCNA exam
