Providing virtualized visibility through routers

摘要

A method implemented by a network element to track IPv6 addresses of devices in a home network wherein the network element provides DHCPv6 service to the home network and a home network router on the home network assigns IPv6 address to the devices using a prefix provided by the DHCPv6 service the method including receiving a DHCPv6 request for a prefix delegation from a home network router sending a DHCPv6 message including an assigned prefix to the home network router the DHCPv6 message including a request for notification of configured IPv6 addresses receiving a first ICMP message from the home network router including a MAC address and corresponding IPv6 address for a configured device and sending the home network router a second ICMP message to acknowledge recording the IPv6 address for the configured device enabling the network element to provide services and forward traffic directly to the configured device.
