The basic configuratio n of EIGRP is so similar to the basic configuration of IGRP that instructors occasionally will instruct beginners to “configure IGRP, but add an E.” As mentioned in the previous section, the metric weights command is used the same way with EIGRP and IGRP. The traffic-share and variance commands are also used identically. For a review of these commands, please refer to Chapter 6.
The case studies in this section demonstrate a basic EIGRP configuration and then examine summarization techniques and interoperability with IGRP.
Like IGRP, EIGRP requires only two steps to begin the routing process:
Enable EIGRP with the command router eigrp process-id.
