• 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:
• T h e h o s t s i n N 1 c a n j o i n o n l y t h e m u l t i c a s t g r o u p 224 .1.1.1.
• The hosts in N2 can join any multicast groups.

# On Router A, enable IP multicast routing.
<RouterA> system-view
[RouterA] multicast routing
[RouterA-mrib] quit
# Enable IGMP on GigabitEthernet 2/1/1.
