Protocol Independent Multicast
Protocol independent multicast (PIM) is a group of multicast routing protocols that provides one-to-many and many-to-many
transmission of information. PIM uses routing information from other routing protocols and does not depend on any specific
unicast routing protocol. PIM uses any unicast routing protocol that is deployed in the network. OS10 supports the following PIM
modes:
● PIM sparse mode (PIM-SM)
● PIM source specific multicast (PIM-SSM)

Terminology Definition
Rendezvous point (RP) The RP is a single root node that the shared tree uses, called the rendezvous point.
(*, G)
(*, G) refers to an entry in the PIM table for a group.
(S, G)
(S, G) refers to an entry in the PIM table for a source and group on the RP tree
(RPT).
(S, G, RPT)
(S, G, RPT) refers to an entry in the RP tree.
First hop router (FHR) The FHR is the router that is directly connected to the multicast source.
Last hop router (LHR) The LHR is the last router in the multicast path and is directly connected to the
multicast receiver.
Intermediate router A PIM router that is not an FHR, RP, or LHR.
Shared tree (RPT) The RPT is an unidirectional multicast tree whose root node is the RP.
Shortest path tree (SPT) The root node of the SPT is the multicast source. The multicast traffic routes to the
receiver on the shortest path. This setup reduces network latency and traffic
congestion at the RP.
Outgoing interface (OIF) The OIF is the interface through which a multicast packet is sent out towards the
receiver.
Incoming interface (IIF) The IIF is the interface through which a multicast packet is received towards the
source or the RP.
Reverse path forwarding (RPF) The RPF is the path the router uses to reach the RP or the multicast source.
