  1. Multicast service delivery in PMIPv6 domainsdraft-contreras-multimob-msd-00 L.M. Contreras, C.J. Bernardos, I. Soto Universidad Carlos III de Madrid (UC3M) Hiroshima, MULTIMOB WG, 2009-11-12 draft-contreras-multimob-msd-00

  2. Key points • MAG maintains the MNs multicast status • MAG as MN’s first-hop • LMA(-unicast) is not strictly required for multicast traffic management • MAG as MLD proxy: LMA receives a summary of MNs subscriptions (no vision of individual subscriptions) • MAG as multicast router: multicast traffic management local at MAG • MN keeps IP address as it moves • MNs always reachable through LMA based on MN-HoA draft-contreras-multimob-msd-00
