ABSTRACT:
The invention is directed to providing NDP mediation over an IP interworking VLL. ICMPv6 Neighbor Discovery and Inverse Neighbor Discovery messages are intercepted by provider edge (PE) devices to learn both IPv6 interface addresses and link-layer addresses of customer edge (CE) devices before forwarding the messages to the CE devices, and in some cases after altering the messages to make them more meaningful to the receiving CE devices. In this manner, the CE device interface addresses do not need to be communicated over the LDP control link, as in IPv4 ARP Mediation.
