FIGURE 112 MRP ring with switch B as the querier
In the scenarios shown in Figure 111 and Figure 112 , a topology change notification is sent to the
MRP ring master, which forces an advertisement of the IGMP query to the entire network upon
receiving the notification. This reduces the failover time for the multicast streams over a ring
topology without the need of lowering the IGMP query interval or IGMP group membership time.
