IPexpert Volume 1 section 5 - L2 protocol tunneling

Not gonna say much here just that this teeny lab kicked my butt. I must say I fell pretty comfortable when it comes time do anything with BGP, OSPF, EIGRP and routing. Even multicast and IPv6 I feel comfortable now. QoS, I am getting there. I thought l2tunneling was cake until I started this lab. That was Sunday. Today is Wednesday and I finally hammered it out. Two online rack sessions and a bunch of researching in between. I didn't just follow the proctor guide on this!

I tried it my own way - didn't work.
Tried to fix it - didn't work.
Saved configs
I copied the final configs to the switches just to make sure the solution worked - it worked.
Recopied my configs over and progressed from their.

Repeat about a dozen times.

Troubleshooting, debugging, I learned a lot along the way.

I even found out a lot about how LACP works, by exchanging your mac and the partner mac - a lot like the OSPF adjacency INIT stage.

Also, the solution doesn't quite follow what you read in the DocCD, another reason it is good to get a taste of more than one vendor, because there are many ways of doing everything.

I swear I know this lab inside-out. It's got me searching for different scenarios. Hopefully come lab time, I am well prepared for anything.
