Configuration procedure
1.
Configure the IP address and subnet mask for each interface as per
. (Details not shown.)
2.
Configure OSPF on the switches to make sure the network-layer is interoperable among the
switches, and routing information between the switches can be dynamically updated. (Details not
shown.)
3.
Enable IP multicast routing, and enable PIM-SM and IGMP:
# Enable IP multicast routing on Switch B, enable PIM-SM on each interface, and enable IGMP on
the host-side interface VLAN-interface 100.
[SwitchB] multicast routing-enable
[SwitchB] interface vlan-interface 100
[SwitchB-Vlan-interface100] igmp enable
[SwitchB-Vlan-interface100] pim sm
[SwitchB-Vlan-interface100] quit
[SwitchB] interface vlan-interface 103
[SwitchB-Vlan-interface103] pim sm
[SwitchB-Vlan-interface103] quit
[SwitchB] interface Vlan-interface 101
[SwitchB-Vlan-interface101] pim sm
[SwitchB-Vlan-interface101] quit
[SwitchB] interface loopback 0
[SwitchB-LoopBack0] pim sm
[SwitchB-LoopBack0] quit
[SwitchB] interface loopback 10
[SwitchB-LoopBack10] pim sm
[SwitchB-LoopBack10] quit
[SwitchB] interface loopback 20
[SwitchB-LoopBack20] pim sm
[SwitchB-LoopBack20] quit
# Enable IP multicast routing, PIM-SM, and IGMP on Switch A, Switch C, Switch D, and Switch E
in the same way. (Details not shown.)
4.
Configure C-BSRs and C-RPs:
# Configure Loopback 10 as a C-BSR and Loopback 20 as a C-RP on Switch B.
