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. After receiving the multicast data, the receiver-side DR determines whether to initiate an RPT-to-SPT … WebSPT switchover allows an LHR to bypass the RP in the data path. SPT switchover is on by default. This means that the RP is really only used for the initial traffic flow. After the first …

WebSwitchover to SPT In an IPv6 PIM-SM domain, an IPv6 multicast group corresponds to one RP and one RPT. Before the switchover to SPT occurs, the DR at the IPv6 multicast source side encapsulates all multicast data destined to the multicast group in register messages and sends these messages to the RP. WebSupermicro switches support both PIM-SM and PIM-DM. An IP multicast routing table can hold 2550 entries, which includes 255 groups and 10 sources per group. PIM requires a …

WebIn the previous article, we covered PIM-SM. We saw that in certain cases, traffic does not follow the optimal path. This is because traffic must flow through the RP. By using the SPT (shortest path tree) switchover feature, a LHR can switchover to … WebShortest-path tree (SPT) SPTs are especially useful in high data-rate applications where reducing unnecessary traffic concentrations and throughput delays are significant. In the default PIM-SM configuration, SPT operation is automatically enabled. (The software includes an option to disable SPT operation. Shortest-path tree operation

WebTo resolve this problem, PIM-SM allows the RP or the receiver DR to trigger an SPT switchover. SPT switchover triggered by the RP After receiving a Register message from the source DR, the RP decapsulates the Register message and forwards multicast packets along the RPT to group members.
