Host A has left multicast group G, and 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 Router B with that displayed on the firewall, you can see that the firewall
acts now as the RP for Source 2 and Host B.
# Display the PIM routing information on Router B.
[RouterB] display pim routing-table
No information is output on Router B.
# Display PIM routing information on the firewall.

SA message filtering configuration
Network requirements
As shown in Figure 356, three PIM-SM domains exist in the network, and OSPF runs within and among
the domains to provide unicast routing.
Configure respective Loopback 0 of Router A, Router C and the firewall as a C-BSR and C-RP in the
respective PIM-SM domain.
Set up an MSDP peering relationship between Router A and Router C and between Router C and the
firewall.
