IP MULTICAST ROUTING
Radhika Rengaswamy
OUTLINE
What is Multicasting?
IP Multicast Addressing
IGMP
Multicast Forwarding Algorithms
Simple, Source-Based Tree, Shared-Tree
Multicast Routing Protocols
Dense-mode (DVMRP, MOSPF, PIM - DM)
Sparse-mode (PIM - SM, CBT)
Time To Live (TTL)
Scope-limiting parameter for IP Multicast datagrams
Controls the number of hops that a IP Multicast packet is allowed to propagate
TTL = 1: local network multicast
TTL > 1: Multicast router(s) attached to the local network forward IP Multicast datagrams
