Abstract:
A Pseudo-Wire to Virtual Private Network Provider Edge (PW-VPN PE) router (300) has a pseudo-wire (PW) element (302), a virtual routing and forwarding (VRF) element (304) integrally coupled to the PW element, and a controller (306) for controlling operations of the PW and the VRF elements. The controller is programmed to receive (408-414) a layer 3 (L3) packet comprising a frame and an embedded L3 packet, and transmit (416) to a targeted network element on a virtual circuit a new frame with the embedded L3 packet.
