i have a media gateway and a softswitch. The traffic cross a red IP/MPLS. We want to separate the voice in a vrf and the signaling in other vrf. The vrf is created in the PE router. do you have information about this?
You can configure it as a normal MPLS VPN setup with the proper VRFs and sub-interfaces on the PE routers with sub-interfaces. Also enabling of MPLS on an interface does not stop IP forwarding, i.e. an MPLS enabled interface can have both, IP and MPLS neighbors at the same time.
