Configuration procedure
1. Configure the IP address and subnet mask for each interface as per Figure 48. (Details not shown.)
2. Configure OSPF on the switches in the PIM-SM domain to make sure they are interoperable at the
network layer. (Details not shown.)
3. Enable IP multicast routing and administrative scoping, and enable IGMP and PIM-SM:
# Enable IP multicast routing and administrative scoping on Switch A, enable IGMP on
VLAN-interface 100, and enable PIM-SM on each interface.
<SwitchA> system-view
[SwitchA] multicast routing-enable
[SwitchA] pim
[SwitchA-pim] c-bsr admin-scope
[SwitchA-pim] quit
[SwitchA] interface vlan-interface 100
[SwitchA-Vlan-interface100] igmp enable
[SwitchA-Vlan-interface100] pim sm
[SwitchA-Vlan-interface100] quit
[SwitchA] interface vlan-interface 101
[SwitchA-Vlan-interface101] pim sm
[SwitchA-Vlan-interface101] quit
# Enable IP multicast routing and administrative scoping, and enable IGMP and PIM-SM on Switch
E and Switch I in the same way. (Details not shown.)
# On Switch B, enable IP multicast routing and administrative scoping, and enable PIM-SM on
each interface.
<SwitchB> system-view
[SwitchB] multicast routing-enable
[SwitchB] pim
[SwitchB-pim] c-bsr admin-scope
[SwitchB-pim] quit
[SwitchB] interface vlan-interface 200
[SwitchB-Vlan-interface200] pim sm
[SwitchB-Vlan-interface200] quit
[SwitchB] interface vlan-interface 101
[SwitchB-Vlan-interface101] pim sm
[SwitchB-Vlan-interface101] quit
[SwitchB] interface vlan-interface 102
[SwitchB-Vlan-interface102] pim sm
[SwitchB-Vlan-interface102] quit
[SwitchB] interface vlan-interface 103
[SwitchB-Vlan-interface103] pim sm
[SwitchB-Vlan-interface103] quit
# Enable IP multicast routing and administrative scoping, and enable PIM-SM on Switch C, Switch
D, Switch F, Switch G, and Switch H in the same way. (Details not shown.)
4. Configure an admin-scope zone boundary:
