The output shows that Router D now acts as the RP for Source 2 and Host B.
SA message filtering configuration
Network requirements
As shown in Figure 55, OSPF runs within and among the PIM-SM domains to provide unicast routing.
Set up an MSDP peering relationship between Router A and Router C and between Router C and Router
D.
Source 1 sends multicast data to multicast groups 225.1.1.0/30 and 226.1.1.0/30. Source 2 sends
multicast data to the multicast group 227.1.1.0/30.
Configure SA message filtering rules so that:
• Host A and Host B receive the multicast data only addressed to multicast groups 225.1.1.0/30 and
226 .1.1. 0 / 3 0 .
• Host C receives the multicast data only addressed to multicast groups 226.1.1.0/30 and
227.1.1.0 / 3 0 .
