Both POS 5/0 on Router D and GigabitEthernet 0/3 on the firewall act as C-BSRs and C-RPs. The
C-BSR on Router D has a higher priority. The range of multicast groups served by the C-RP is
225.1.1.0/24. Modify the hash mask length to map a certain number of consecutive group
addresses within the range to the two C-RPs.
IGMPv2 runs between Router A and N1 and between Router B, Router C, and N2.

2. Configuration procedure
a. Assign an IP address and subnet mask to each interface according to 2823HFigure 349. (Details not
shown.)
b. Configure OSPF on the routers in the PIM-SM domain to make sure they are interoperable at
the network layer. (Details not shown.)
c. Enable IP multicast routing, IGMP, and PIM-SM:
# On Router A, enable IP multicast routing globally, enable IGMP on Ethernet 1/1, and enable
PIM-SM on each interface.
