Abstract:
In one embodiment, a provider edge (PE) device in a computer network determines an IPv4 address and link-layer address for each adjacent customer premise equipment (CPE) device, and assigns each CPE device a unique IPv6 address. The PE device stores a key-pair mapping between the unique IPv6 address and combined IPv4 and link-layer address for each adjacent CPE, the mapping bound by a CPE session context, and uses the CPE session context to convert between IPv4 and IPv6 for all network traffic to and from a particular CPE device.
