MPLS IP Interworking FR to VLAN?

william.caban · ‎07-20-2007

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

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,

When doing L2VPN interworking, the attachment circuits media type is different on both sides. If it is not then its a plain like-to-like L2VPN.

In your case also it will be like one end on ethernet and the other end on FR. The needed framing reconstruction is done by the egress PE.

PS: do go through the restrictions section of the appropriate interworking secnario to understand whether your setup meets the requirements.
