Abstract
A method performed by a network element for providing micro-mobility in a network to a mobile node including the steps of receiving a registration request message at the mobility anchor point from an access router that is currently coupled to the mobile node, wherein the registration request message includes an endpoint identifier of the mobile node and a local care-of address of the mobile node, establishing a label switch path (LSP) between the mobility anchor point and the access router, storing the endpoint identifier in a binding entry along with the local care-of address, a regional care-of address, the label switch path and an egress interface, advertising the endpoint identifier with associated regional or local care-of address of the mobile node, and forwarding data packets, received at the mobility anchor point from a corresponding node that have the regional or local care-of address, to the mobile node using the LSP.
