RE: ATM-AToM

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
