I just uploaded a brand new EIGRP Troubleshooting lab which pretty much covers all the nasty things that can happen to EIGRP. It's a preconfigured configuration with a bunch of routers and the goals are basically 'trouble tickets'. If you think you are good at EIGRP then i challenge you to give it a go, see if you can solve it without using show run but only commands like 'show eigrp' , 'show ip route' and the appropiate 'debug' commands. This will teach you exactly the skills you need to troubleshoot networks in real life, beat the CCNP TSHOOT exam or troubleshooting skills needed for a CCIE.
This one took a lot more work to create then the other labs, since I had to think about creating scenarios without messing up the previous configurations.
Hopefully you like it, please let me know what you think of it...there's no video solution / final config at this moment but questions can of course be asked in the forum :)
Take care and good luck!
