[nsp] atm question

[Brian Turnbow]

Hello everyone,
I have 3 3725s connect to each other  on an stm-1 usng the NM ATM oc3 module
and I have a question.
the 3725s have 2 FE ports one that will be connected to the internal
networks and one used for internet connectivity.
I need to create a situation where the private and public traffic is
segregated.
My first thought is to use mpls vpn, but as I'm not an ATM expert I wanted
to know if there was a way to "map"
the FEs to different PVCs. I know I could do this with policy routing but
are there any other methods?

thanks
Brian
