IGMPv2 runs between Router A and N1, and between the other two routers and N2. Router A acts
•
as the IGMP querier in N1. Router B acts as the IGMP querier in N2 because it has a lower IP
address.
Configure the routers to meet the following requirements:
The hosts in N1 can join only the multicast group 224.1.1.1.
•
The hosts in N2 can join any multicast groups.

PIM network
Configuration procedure
1. Assign an IP address and subnet mask to each interface according to
shown.)
2. Configure OSPF on the routers of the PIM network to make sure the following conditions are met:
(Details not shown.)
The routers are interoperable at the network layer.
The routers can dynamically update their routing information.
3. Enable IP multicast routing, and enable IGMP and PIM-DM:
# On Router A, enable IP multicast routing.
<RouterA> system-view
[RouterA] multicast routing
[RouterA-mrib] quit
# Enable IGMP on GigabitEthernet 2/1/1.
[RouterA] interface gigabitethernet 2/1/1
[RouterA-GigabitEthernet2/1/1] igmp enable
[RouterA-GigabitEthernet2/1/1] quit
# Enable PIM-DM on GigabitEthernet 2/1/2.
