PIM

PIM is a multicast routing architecture that allows the addition of IP multicast routing on existing IP networks. Multicast IP routing protocols are used to distribute data to multiple recipients. Using multicast, a source can send a single copy of data to a single multicast address, which is then distributed to an entire group of recipients. A multicast group identifies a set of recipients that are interested in a particular data stream, and is represented by an IP address from a well-defined range. Data sent to this IP address is forwarded to all members of the multicast group.

PIM is a unicast routing protocol independent and can be operated in two modes: dense and sparse (currently, only sparse mode is supported) It is designed to provide scalable inter-domain multicast routing across the Internet. PIM provides multicast routing and forwarding capability to the switch. It maintains the integrity of the hardware based multicast forwarding table with respect to the forwarding table existing in the software. It is independent of the underlying unicast routing protocol and uses the information from the unicast routing protocol.
