20.1 PIM Configuration

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). Black Box 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.

The general PIM commands supported in this release are:
