Hi

I am trying to understand the build we have on our CE routers from the Service Provider. Frame-relay encapsulation is build on the Wan interface with LMI configured/dlci enabled on sub-interface. At the PE end, there is also Frame-relay configuration on the PE end...How does that work? Does Cisco have any docs that I could read?

Hello Mary,

on the PE router there is a Frame-relay interface and sub-interfaces.

the PE-CE link is the VRF access link what is different on the PE side is the presence of the command ip vrf forwarding VRF-name in the correct FR subif.

Then the MPLS cloud includes the backbone links of the PE routers.


see the following link for an introduction to MPLS VPN

Hope to help

Giuseppe
