These labs are killing me! I get to the rougher parts in labs 3 and 4 and it's one thing after another. It seems that I get 90% to the end of the solution and then draw a blank. Spend the next 30 minutes to an hour trying to figure it out and finally looking at the solution to find - for example - that yes there was that one command under the isis process that I didn't have that somehow broke the whole Traffic Engineering tunnel. And the tunnel output commands don't seem to tell me anything relevant to the problem at hand. What happened to the days when you could just hit things and make them work. I think I'm gonna go run over one of my routers now. If anyone has any better ways of dealing with lab stress/irritation, please let me know!
Although I am half kidding, it really would be interesting/helpful to hear if any of you have had similar problems and found ways to deal with it.
Enjoy,
Jason
