Abstract: Techniques are provided for seamless integration of wired and wireless functionality packet forwarding in network. A plurality of access switches are provided in each of a plurality of mobility sub-domains that are part of a mobility domain of a network. Each access switch serves one or more Internet Protocol (IP) subnets, each comprising a plurality of IP addresses. An access switch obtains an IP address for a wireless device according to the one or more IP subnets that the access switch serves. The access switch sends an association advertisement message to indicate the IP address of the wireless device and to enable other access switches and routers to compute a path to the wireless device. When a wireless device obtains an IP address, it can keep the same IP address as it roams in the mobility domain.
