EIGRP troubleshooting demo

- [Instructor] So we made EIGRP work,…but what if it didn't work?…Like, what if something went wrong in the process?…What are our options?…What are we going to do?…Well, the very first thing I would like you to do…is show IP route.…Figure out what the issue is.…What routes am I not learning?…You can see here we have 10.60.0.0.24.…That's what I expect to see.…If I didn't see that route there, I'd be a little worried.…So, okay, what else can we look at?…Say I'm not seeing the routes I need to see.…

Where do I need to go?…One of the first places is show IP interface brief.…Now a lot of the older guys right now are going,…What? No, you don't do that.…Yes, you do and here's why.…Check to see if the interface is up.…That's an easy win for the troubleshooting process, right?…This can happen.…An interface can go down.…Somebody could've accidentally shut it down.…Turning it back on.…Very simple fix.…Don't forget the simple fixes…when you're in the troubleshooting process.…Another command I would like you to know…is show EIGRP neighbors.…
