Abstract:
1. An apparatus for forwarding link-layer frame information to a third node, comprising: a circuitry comprising functional modules, a memory, and a processor; the circuitry configured to receive, from a first node in a first addressing domain, a link-layer frame comprising a first packet portion, a first link layer identifier and a second link-layer identifier that uniquely identifies the third node, the circuitry being further configured to identify a first set of stored information with forwarding information for the first packet portion based on the first and second link-layer identifiers, wherein the forwarding information comprises a third node identifier and a third node address, wherein the third node identifier identifies one of multiple addressing domains of the third node, the circuitry being further configured to generate a first redirecting packet with header information from the first packet portion and the identified third node identifier and transmit the first redirecting packet towards the third node identified by the third node address, wherein the first node and the apparatus are located in the first addressing domain, wherein the first node has a first home address that includes an address prefix corresponding to an addressing domain of the third node, wherein the prefix is included in a first routing advertisement that is transmitted by the third node, wherein the first routing advertisement being associated with a routing system that includes the addressing domain of the third node, and wherein the third node is a mobile Internet Protocol home agent using the routing system that supports at least two addressing domains.
