Re: CCIE-SP TOPIC - trouble establishing neighbor relationship

Ummm i'm not sure how I copied it in the original email but looks like I
pasted the R4 config twice in the email. In my lab the IP configs are
correct. I can ping from one side to the other and I can even establish OSPF
across the two CE sites but not ISIS. Thanks for for everyone who looked at
this for me. I am hoping that maybe I could have someone lab this up and
look at it for me. I have been successfully been able to establish neighbor
relationship with ISIS over Frame really but just not over L2TPv3 and am not
sure why. I will lab this up one more time and send full configs if you
like.
