Network requirements
As shown in
•
OSPF and PIM-DM run on the network.
•
VOD streams are sent to receiver hosts in multicast. Receiver hosts of different organizations
form stub networks N1 and N2. Host A and Host C are receiver hosts in N1 and N2,
respectively.
•
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 multicast group 224.1.1.1.
•
The hosts in N2 can join any multicast groups.
