I was sent a question (below) that I think that you that are more ATM aware might be able to help with if you will...

Thank you

I have had numerous discussions with co-workers on how to implement MPLS over an existing ATM network.  My initial thought is that it would be beneficial to have an MPLS aware ATM function in the LER.  This would allow the control of the ATM plane at the ingress side of the network.  However there are case in which the vendor is not producing MPLS awareness into their ATM support.  If that's the case then I need to treat the PVC as just that, however I am a little fuzzy on how that would work and how the label gets carried to the LSR.  Any suggestions. Thanks.
