WebJan 19, 2024 · PIM-SM is used in a multicast network when relatively few devices are involved in each multicast and these devices do not forward multicast packets for a group, unless there is an explicit request for the traffic. PIM-SM distributes information about active sources by forwarding data packets on the shared tree.

WebPIM is used for multicast routing within the network. Devices in the network can receive the multicast feed requested and non-participating routers can be pruned. The router OS supports PIM sparse mode (PIM-SM). Default not enabled interface Syntax [ no] interface ip-int-name Context config>router>pim Description WebPIM-SM works via the use of an RP (Rendezvous Point). Let us look at the process that PIM-SM takes: 1. Shared Tree (RP to Receiver) - The receiver sends an IGMP Join message to the first hop router (FHR), i.e its direct neighboring router. This … WebPIM-SM is a pull multicast distribution method; multicast traffic only goes through the network if receivers explicitly ask for it. When a receiver pulls multicast traffic, ...

PIM-SM has the capability for last hop routers (routers directly connected to members) to switch to the Shortest Path Tree and bypass the RP if the traffic rate is above a set threshold called the SPT-Threshold.

WebApr 14, 2008 · Re: multicast - Will PIM-SM do spt switchover even without an RP. Just a clarification. If the stream was already started before you applied the accept-rp, you need to stop the receiver and clear the mroute on r3 and r5. Otherwise, the join will go up the SPT and the accept-rp has no effect. WebJan 19, 2024 · Such events include liveness checking, shortest path tree (SPT) switchover, and PIM asserts.

WebThe join message travels hop by hop toward the multicast source, and the SPT is established across the PIM-SM domains. The subsequent multicast data flows to RP 2 along the SPT, and from RP 2 to the receiver-side DR along the RPT.
