RE: ATM-AToM

This doesn't make sense. You have to use L3 endpoints for the xconnect
command. What is that endpoint? You need to provide configurations and
more details on this because either I don't understand your setup or you are
not understanding my recommendations.

Dear Tyson,

what if there is no layer 3 information between PE Router and the customer
Router,only layer 2 ATM circuit and we are offering them 2 Layer 2 AToM
circuit for redundancy.

How can i do that??beside i can't do any changes at the Customer Router.

I appreciate helping me in this case.

Thanks,

Osama
