RE: CCIE-SP TOPIC - trouble establishing neighbor relationship

Why are you doing interworking ? You have frame-relay in both sides, right ?
Remove it and it should work.

Subject: Re: CCIE-SP TOPIC - trouble establishing neighbor relationship
using ISIS over Frame-relay across L2TPv3

Just lab'ed it up again and still same result. I'm not sure what I'm
missing. I think I was alittle more careful this time on what I am copying
and pasting. Please take a look again and let me know what does anyone
think.
