Re: ISIS Level-11 router + MPLS Labels for Level-2 Loopbacks

Thank you guys. There is nothing wrong with redistributing L2 into L1, that
works fine as I get LSP to work as expected. I was just asking myself if in
the exam one of the conditions was for us not to do redistribution, what
more option we have.

Thank you, I will try the recommendations as posted by everybody on this
thread.

Regards
SP
