MPLS IP Interworking FR to VLAN?

william.caban · ‎07-20-2007

(I re-posted this question in the MPLS forum where it should be)

If I do Frame Relay to VLAN over L2TPV3 as the example in this document:

http://www.cisco.com/en/US/products/sw/iosswrel/ps1829/products_feature_guide09186a00801b2407.html#wp1046329

Do I have to xconnect back to frame-relay to finish the circuit or can I use the "interface VLAN" somewhere else in the network and have the circuit to behave like a point-to-point even when in started as frame-relay.

Or the question might be better state as: If the client can have FR delivered on one side and Ethernet in the other?

Thanks,

The example in the given link sets up Multilink Frame Relay interfaces to perform Frame Relay-to-Ethernet interworking between PE routers. The example uses IP interworking, also referred to as routed interworking.

I'm confused, will this configuration will route the IP and would I be able to deliver pure IP or will I still need to do some type of frame-relay conversion in order to deliver it?

FR emulation of some sort would have to be used. Alternatively, you can start tunnel on another interface, that is not FR.

How can I do this FR emulation? Is there a way or do I have to deliver to a FR interface?

We posted at about the same time with Gabriel.

What Gabriel suggested seems an exact solution that you require, as per Cisco document located at the link he provided.
