I was reading the documentation on reflexive ACLs (trying to shore up my security weaknesses) and ran across this:
This example shows Enhanced IGRP permitted on the interface.
HUH? What the hell is that?
DOH! EIGRP. I don’t think that I’ve seen it written like that in a LONG time. I also misread it as “Enhanced IGMP” at first.
I really need to be done with studying. 🙂
