Config Museum: EIGRP Config Answers

By Chris March 14, 2014 11:55

This #CCNA exercise was a straightforward EIGRP config exercise. The config is below the line.


As a quick review of the configuration concepts… first, EIGRP requires a numeric parameter, the autonomous system number (ASN), on the router eigrp command. It just needs to match on all the routers that want to exchange routes. Then, you can use the network command  with glassful network numbers, to identify the local router’s interfaces in that same network, enabling EIGRP on those interfaces. Finally, use the passive-interface command to then disable EIGRP from forming neighbor relationships on that interface, as a simple but effective security measure.

Example 1 shows the same steps that could be used on all three routers in this case.

Example 1: R1, R2, and R3 EIGRP Configuration


That’s it! nice and clean. More EIGRP coming up in the next config museum post!
