I finished that lab a few weeks ago. All I can say is it was a bugger to
solve. The IE message board has some good insight into why it was
occurring. I believe turning off interface keep-alives resolved the looping
problem. I believe it was SW4, F0/13, F0/15, F0/19, F0/21. Also, I tried
doing L2protocol-tunnel on STP also...

Hi Gang,
Has anyone done internetwork expert's lab 20 recently? I am having a hard
time on the first section with STP where it keeps flipping interfaces to
err-disabled mode due to 'loopback error'. I am wondering if anyone was able
to solve it.
Thanks!
