Method and apparatus for facilitating network mobility

A method for facilitating network mobility comprising:

• sending a message by a network node via a link layer switched network to one of a plurality of network devices coupled to the link layer switched network to establish a data path for a remote unit served by the network node,
• wherein the message is a link layer message and comprises a source link layer address that is uniquely associated with the remote unit,
• wherein the network device comprises one of an access router (AR) and a foreign agent (FA) of the remote unit, and
• wherein the data path being between the network node and the network device for enabling data from the network device destined to the remote unit through the network node.

A network node comprising:

• a transceiver;
• a network interface;
• and
• a processing unit, communicatively coupled to the transceiver and the network interface,
• adapted to receive, via the transceiver, signaling to facilitate wireless connectivity of a remote unit via the network node wherein the network node is coupled to a link layer switched network,
• adapted to send, via the network interface to the link layer switched network, a message to one of a plurality of network devices coupled to the link layer switched network in response to receiving the signaling,
• wherein the message is a link layer message and comprises a source link layer address that is uniquely associated with the remote unit and wherein the message establishing a data path associated with the remote unit, and
• wherein the data path being between the network node and the network device for enabling data from the network device destined for the remote unit through the network node.
