Mobility Bindings associate Mobility Label, a Mobile Node’s IP Address or Routing Prefix and a Serving LER’s Router ID (“Origin NEXT_HOP”) Carried as Network Layer Reachability Information (NLRI) using MP-BGP UPDATE messages and encoded as the Address Family structure in the MP-REACH-NLRI New types of MP-BGP Address Families are proposed – IPv4 Mobility Address Family, IPv6 Mobility Address Family following the format in RFC 4760 – “Multi-Protocol Extensions for BGP-4” May contain additional information such as the Mobile Node’s priority which can be communicated during the registration process Two types of Mobility Binding Structures are proposed: Mobile Host Mobility Binding and Mobile Router Mobility Binding Traffic delivery uses stacked MPLS labels: outer infrastructure label (LER-to-LER) and inner label (Mobility Label) to identify the Mobile Node Mobility Bindings and Traffic Delivery Traffic delivery using stacked labels |
