While working on IE Lab 8, I found something interesting. I mistakenly
entered duplicate EIGRP router ID's on router 4 and router 5. No matter
what I tried the routing table on R4 refused to enter EIGRP External routes
into its routing tables.
I noticed in debugs that the route was given a max metric of 4294967295, but
I couldn't find out why until I used the undocumented command "sh ip eigrp
events" to find the problem. Here is what finally clued me in.
488 00:15:00.727 Ignored route, neighbor info: 174.1.145.1 Serial1/1
489 00:15:00.727 I*gnored route, dup router: 150.1.5.5*
490 00:14:56.483 Ignored route, metric: 9.9.9.9 2561024256
491 00:14:56.483 Ignored route, neighbor info: 174.1.145.1 Serial1/1
492 00:14:56.483 Ignored route, dup router: 150.1.5.5
The most interesting thing was that internal routes were accepted, but
external routes failed. I prefer the OSPF method for dealing with duplicate
router id's much better.
Hope this helps someone else.
