(Details not shown.)
{ The switches are interoperable at the network layer.
{ The switches can dynamically update their routing information.
3. Enable IP multicast routing, IGMP, and PIM-SM:
# On Switch A, enable IP multicast routing.
<SwitchA> system-view
[SwitchA] multicast routing
[SwitchA-mrib] quit
# Enable IGMPv3 on VLAN-interface 100 (the interface that connects to the receiver host).
[SwitchA] interface vlan-interface 100
[SwitchA-Vlan-interface100] igmp enable
[SwitchA-Vlan-interface100] igmp version 3
[SwitchA-Vlan-interface100] quit
# Enable PIM-SM on the other interfaces.
[SwitchA] interface vlan-interface 101
[SwitchA-Vlan-interface101] pim sm
[SwitchA-Vlan-interface101] quit
[SwitchA] interface vlan-interface 102
[SwitchA-Vlan-interface102] pim sm
[SwitchA-Vlan-interface102] quit
# Enable IP multicast routing, IGMP, and PIM-SM on Switch B and Switch C in the same way
Switch A is configured. (Details not shown.)
# Enable IP multicast routing and PIM-SM on Switch D and Switch E in the same way Switch A is
configured. (Details not shown.)
4. Configure the SSM group range:
# Configure the SSM group range to be 232.1.1.0/24 on Switch A.
[SwitchA] acl number 2000
[SwitchA-acl-basic-2000] rule permit source 232.1.1.0 0.0.0.255
[SwitchA-acl-basic-2000] quit
[SwitchA] pim
[SwitchA-pim] ssm-policy 2000
[SwitchA-pim] quit
# Configure the SSM group range on Switch B, Switch C, Switch D, and Switch E in the same way
Switch A is configured. (Details not shown.)
