No information is output on Switch D.
Host A has left multicast group G. Source 1 has stopped sending multicast data to multicast group G.
When Source 2 10.110.6.100/24 sends multicast data to G, Host B joins G. By comparing the PIM
routing information displayed on Switch B with that displayed on Switch D, you can see that Switch D acts
now as the RP for Source 2 and Host B.

SA message filtering configuration
Network requirements
As shown in Figure 65, three PIM-SM domains exist in the network, and OSPF runs within and among the
domains to provide unicast routing.
Loopback 0 is configured as a C-BSR and a C-RP in the related PIM-SM domains on Switch A, Switch C,
and Switch D, respectively.
