MPLS and FR

All,

Where does a FR switch sit in relation to a provider's network? Does it sit on the edge or behind a router? If it sits on the edge, how do I keep the customers in a VRF? Do I only map from the customers perspective to the PE router?

Example:

PE1 ----> FR SW ---> Customer 1

                 |________Customer 2

I'm assuming that in the FR switch, I'd have dlci PE1 --> Customer1 and PE1 --> Customer2. Is that all that's required? What about LMI and Inverse ARP? Disable?

HTH, John *** Please rate all useful posts ***

PE can itself offer Frame Relay encapsulation to CE.
