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) PIM terminology Table 19. PIM terminology Terminology Rendezvous point (RP) (*, G) (S, G) (S, G, RPT) First hop router (FHR) Last hop router (LHR) Intermediate router Shared tree (RPT) Shortest path tree (SPT) Definition The RP is a single root node that the shared tree uses, called the rendezvous point. (*, G) refers to an entry in the PIM table for a group. (S, G) refers to an entry in the PIM table for a source and group on the RP tree (RPT). (S, G, RPT) refers to an entry in the RP tree. The FHR is the router that is directly connected to the multicast source. The LHR is the last router in the multicast path and is directly connected to the multicast receiver. A PIM router that is not an FHR, RP, or LHR. The RPT is an unidirectional multicast tree whose root node is the RP. 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. 644 Multicast
