  1. BGP for P2MP draft-satoru-mpls-bgp-multipoint-05.txt Satoru Matsushima SOFTBANK TELECOM

  2. History • 00 version • 2005/02 • First presentation • 64th IETF at Vancouver in 2005 • Last version (-05) • Add motivation and some use cases • Just left out protocol details

  3. Overview (1) • Motivations • Many unicast MPLS and unicast MPLS-VPN domains are inter-connected by BGP (RFC3107) • Realistically, BGP is needed for unicast-LSP, AND P2MP-LSP • Use cases • Inter-AS P2MP-LSP for “Option.C” and “Carriers’ carrier” multicast VPNs • Intra-AS P2MP-LSP over unicast LSP to keep existing network simple

  4. Overview (2) • Goals • Clarify and find out what enhancements P2MP requires to BGP • Carrying P2MP-LSP info and labels • Discovering root/branch/leaf nodes • Key points • Focus on purely P2MP transport (application agnostic) • Scalability

  5. Next steps • We need more feedback to keep moving forward! • Need more concrete requirements and use cases ? • Comments or contributions are welcome • I would like to move document to WG document
