WebSPT Switchover. 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. Should this value be set to zero, the default behaviour for the PIM-SM leaf routers attatched to active receivers is ...

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.

"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. " - Pim-sm spt switchover

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. When the transmission rate of multicast data packets reaches 1024 kbit/s, the SPT switchover is performed. After the SPT switchover, the path through which HostA receives multicast packets is Source-RouterB-RouterC-HostA. Figure 4-21 Network diagram for performing SPT switchover in PIM-SM domain.

WebSPT Switchover. A multicast group on a PIM-SM network can be associated with only one RP and sets up only one RPT. Normally, all multicast packets destined for a multicast group are encapsulated in Register messages and sent to the RP. The RP then decapsulates the packets and forwards them along the RPT to multicast group members. 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 …

WebPIM Sparse Mode (PIM-SM) is a pull multicast distribution method; multicast traffic is only sent through the network if receivers explicitly ask for it.
