[c-nsp] VRF-aware Circuit emulation?

[Hughes, Scott GRE/MG]

This is for an enterprise disaster-recovery scenario. The configuration is simplistic -- http://scotthughes.org/cem-failover

To clarify, I'm talking about Circuit Emulation on ISR routers. I want to emulate analog circuits using a SONET-protected Ethernet VLAN as IP backhaul. The ISR routers are used for various other (different) purposes at all 3 sites (head-end, remote, disaster recovery) and intermixing the routing tables or using route-maps and access-lists would be inconvenient. Running a VRF on a dot1q-tagged interface into the SONET would be a nice way to keep layer-3 separation for the CEM services. I would also prioritize traffic on that VLAN at the SONET level to ensure QoS.

I'm open to suggestions about alternate ways to approach this. Obviously, hanging a separate router on a VLAN solely for this purpose is inefficient (and what I'm trying to avoid)

Hi Scott,

To some degree, this would be rather odd to do as CES is a point-to-point solution and is used to transport TDM traffic. 

Please clarify why you would do this?

Does anyone know if Circuit emulation using NM-CEM-4TE1 cards supports the xconnects inside a VRF?
