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 multicast group 227.1.1.0/30.
Configure SA message policies to meet the following requirements:
Host A and Host B receive the multicast data only addressed to multicast groups 225.1.1.0/30
and 226.1.1.0/30.
Host C receives the multicast data only addressed to multicast groups 226.1.1.0/30 and
227.1.1.0/30.

Configuration procedure
1. Assign an IP address and subnet mask to each interface according to Figure 56. (Details not
shown.)
2. Configure OSPF on the routers in the PIM-SM domains. (Details not shown.)
3. Enable IP multicast routing, IGMP, and PIM-SM, and configure a PIM domain border:
