  12. MBONE Key Knowledge • IP multicast • class D IP address, 224.0.0.0 ~ 239.255.255.255 • all systems on this subnet 224.0.0.1 • all routers on this subnet 224.0.0.2 • all DVMRP routers 224.0.0.4 • IP tunnel • IP-in-IP

  13. MBONE Key Knowledge • IGMP (Internet Group Management Protocol) • Join, Query, Report • Leave (IGMPv2) • Group-Source Report (IGMPv3) • IGMP DVMRP (between mrouters) • Multicast Router (mrouter) • Groups database, Multicast routing

  14. MBONE Key Knowledge • DVMRP (Distance Vector Multicast Routing Protocol) • soft-state unicast routing table (single-source shortest path algorithms - Bellman-Ford,..) • RPM (Reverse Path Multicasting) to build per-source-group multicast tree • check source and routing table for RPM • check destination and IGMP database for multicast within this subnet • route exchange, prune, graft, graft ack (via IGMP DVMRP)
