Carrier Supporting Carrier and/or PW termination

Hi Team,

 

I am  trying to find a solution for a scenario where you have 2 customers which are merging their IP backbones.

The customer carrier (CEs) are using private loopbacks and cannot advertise their loopbacks inside the backbone carrier.

The solution to this is to create a sort of Carrier Supporting Carrier solution. Today the customer carrier (CEs) are able to exchange L2 traffic through an end-to-end PW (green one).

But the customer carrier wants to terminate a PW in the backbone carrier PE (red PW) as well for some of their traffic. They are using Cisco as PEs and there are some feature as Pseudowire Headend or Routed Pseudowire.

Do you have any suggestions about what feature to use, or any other option I may not be aware of? which will allow me to terminate some of the traffic at the carrier PE's?

I am attaching some diagram which i have created to show the scenario.

 

Thanks!
