Chapter 31: PIM Quick Configuration

Protocol Independent Multicast (PIM)

Protocol Independent Multicast (PIM) protocols route multicast packets to multicast groups.
PIM is protocol independent because it can leverage whichever unicast routing protocol is used
to populate unicast routing table. There are two modes of PIM protocol – Dense mode (DM)
and Sparse mode (SM). Avaya supports SM only.
PIM-DM floods multicast traffic throughout the network initially and then generates prune
messages as required. PIM-SM attempts to send multicast data only to networks which have
active receivers. This is achieved by having a common Rendezvous Point (RP) known to the
senders and receivers and by forming shared trees from the RP to the receivers.
PIM-SM is described in RFC 2362.
