Abstract
In general, techniques are described for atomically installing and withdrawing host routes along paths connecting network routers to attenuate packet loss for mobile nodes migrating among wireless LAN access networks and a mobile network. In some examples, whenever the mobile node moves from one attachment point to the next, it triggers the distribution of its host route from the new attachment point toward the service provider network hub provider edge (PE) router that anchors the mobile node on a service provider network. Routers participating in the Mobile VPN install the host route 'atomically' from the attachment point to the mobile gateway so as to ensure convergence of the network forwarding plane with the host route toward the new attachment point prior to transitioning mobile node connectivity from a previous attachment point.
