Network Update with Mobility Bindings When a Mobile Node registers with a MSF the serving LER updates the network with a Node’s Mobility Binding carrying the MPLS Label bound to the Node’s IP Address Four Update Methods are proposed Unsolicited Downstream Push. Updates are sent to all peering MSF LER’s. Selective Downstream Push. Updates are send to a pre-defined set of MSF LER’s (such as the Internet Gateways). Predictive Downstream Push. A targeted update is sent to a MSF LER node determined during the forwarding table lookup for a packet sent by a mobile node. Hierarchical On-Demand Distribution. The Mobility Binding update is first sent by a serving MSF LER to a set of Mobility Route Reflectors using the Selective Downstream Push. Once the Mobility Route Reflectors have been updated, all other LER nodes must explicitly request Mobility Labels from the Mobility Route Reflectors for packets destined to a mobile node.
