239No 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 PIMrouting information displayed on Switch B with that displayed on Switch D, you can see that Switch D actsnow as the RP for Source 2 and Host B.# Display PIM routing information on Switch B.[SwitchB] display pim routing-tableNo information is output on Switch B.# Display PIM routing information on Switch D.[SwitchD] display pim routing-tableVPN-Instance: public netTotal 1 (*, G) entry; 1 (S, G) entry(*, 225.1.1.1)RP: 10.1.1.1 (local)Protocol: pim-sm, Flag: WCUpTime: 00:12:07Upstream interface: RegisterUpstream neighbor: NULLRPF prime neighbor: NULLDownstream interface(s) information:Total number of downstreams: 11: Vlan-interface200Protocol: igmp, UpTime: 00:12:07, Expires: -(10.110.6.100, 225.1.1.1)RP: 10.1.1.1 (local)Protocol: pim-sm, Flag: SPT 2MSDP ACTUpTime: 00:40:22Upstream interface: Vlan-interface104Upstream neighbor: 10.110.4.2RPF prime neighbor: 10.110.4.2Downstream interface(s) information:Total number of downstreams: 11: Vlan-interface200Protocol: pim-sm, UpTime: - , Expires: -SA message filtering configurationNetwork requirementsAs shown in Figure 65, three PIM-SM domains exist in the network, and OSPF runs within and among thedomains 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.
