How does PIM SSM work?

PIM source-specific multicast (SSM) uses a subset of PIM sparse mode and IGMP version 3 (IGMPv3) to allow a client to receive multicast traffic directly from the source. PIM SSM uses the PIM sparse-mode functionality to create an SPT between the receiver and the source, but builds the SPT without the help of an RP.

What is IP PIM SSM range?

The software allows SSM configuration for an arbitrary subset of the IP multicast address range from 224.0. 0.0 through 239.255. 255.255.

What is a PIM message?

Protocol Independent Multicast (PIM) is a collection of multicast routing protocols, each optimized for a different environment. PIM control messages are sent as raw IP datagrams (protocol number 103), either multicast to the link-local ALL PIM ROUTERS multicast group, or unicast to a specific destination.

What is IP multicast boundary?

The IP multicast boundary feature is designed to selectively allow or disallow multicast flows to configured interfaces. The ip multicast-boundary command allows you to configure a boundary on a PIM enabled interface by defining which multicast groups may not forward packets over a specified interface.

What is PIM dense mode?

Protocol Independent Multicast – Dense Mode (PIM-DM) is a data-driven multicast routing protocol, which builds source-based multicast distribution trees that operate on the Flood- and-Prune principle. It requires unicast-reachability information, but does not depend on a specific unicast routing protocol.

What is a PIM domain?

Protocol-Independent Multicast (PIM) is a family of multicast routing protocols for Internet Protocol (IP) networks that provide one-to-many and many-to-many distribution of data over a LAN, WAN or the Internet. PIM uses the unicast routing table for reverse-path forwarding.

What is the full form of PIM?

A personal information manager (often referred to as a PIM tool or, more simply, a PIM) is a type of application software that functions as a personal organizer. The acronym PIM is now, more commonly, used in reference to personal information management as a field of study.
