HAPTER ONFIGURATION
Router B and Router C connect to N2 through their respective Ethernet 1/0,
■
and to other devices in the PIM domain through their respective POS5/0.
IGMPv3 is required between Router A and N1. IGMPv2 is required between the
■
other two routers and N2, with Router B as the IGMP querier.

Configuration procedure
1 Configure the IP addresses of the router interfaces and configure a unicast routing
protocol
Configure the IP address and subnet mask of each interface as per
detailed configuration steps are omitted here.
Configure the OSPF protocol for interoperation among the routers. Ensure the
network-layer interoperation among Router A, Router B and Router C on the PIM
network and dynamic update of routing information among the routers through a
unicast routing protocol. The detailed configuration steps are omitted here.
2 Enable IP multicast routing, and enable IGMP on the host-side interfaces
# Enable IP multicast routing on Router A, and enable IGMP (version 3) and
PIM-DM on Ethernet 1/0.
