HP 6125XLG - Configuration Procedure

78
• 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 Switch A and N1, and between the other two switches and N2. Switch A
acts as the IGMP querier in N1.
• Switch B acts as the IGMP querier in N2 because it has a lower IP address.
Configure the switches so that the hosts in N1 can join only the multicast group 224.1.1.1 and the hosts
in N2 can join any multicast groups.

Configuration procedure
1. Assign an IP address and subnet mask to each interface according to Figure 31. (Details not
shown.)
2. Configure OSPF on the switches of the PIM network to meet the following requirements: (Details not
shown.)
{ The switches are interoperable at the network layer.
{ The switches can dynamically update their routing information.
3. Enable IP multicast routing, and enable IGMP and PIM-DM:
# On Switch A, enable IP multicast routing.
<SwitchA> system-view
[SwitchA] multicast routing
[SwitchA-mrib] quit
# Enable IGMP on VLAN-interface 100 (the interface that connects to the stub network).
[SwitchA] interface vlan-interface 100
[SwitchA-Vlan-interface100] igmp enable
[SwitchA-Vlan-interface100] quit
# Enable PIM-DM on VLAN-interface 101.
