Configuration Procedure
1) Configure IP addresses and unicast routing
Configure the IP address and subnet mask for each interface as per
configuration steps are omitted here.
Configure OSPF for interoperation among the switches. Ensure the network-layer interoperation within
and between the PIM-SM domains and ensure dynamic update of routing information among the
switches by leveraging unicast routing. The detailed configuration steps are omitted here.
2) Enable IP multicast routing, PIM-SM and IGMP, and configure a PIM domain border
# On Switch A, enable IP multicast routing, enable PIM-SM on each interface, and enable IGMP on the
host-side interface, VLAN-interface 100.
<SwitchA> system-view
[SwitchA] multicast routing-enable
[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
[SwitchA] interface vlan-interface 102
[SwitchA-Vlan-interface102] pim sm
[SwitchA-Vlan-interface102] quit
[SwitchA] interface loopback 0
[SwitchA-LoopBack0] pim sm
[SwitchA-LoopBack0] quit
The configuration on Switch B, Switch C and Switch D is similar to the configuration on Switch A. The
specific configuration steps are omitted here.
# Configure a PIM domain border on Switch C.
[SwitchC] interface vlan-interface 101
[SwitchC-Vlan-interface101] pim bsr-boundary
[SwitchC-Vlan-interface101] quit
[SwitchC] interface vlan-interface 103
[SwitchC-Vlan-interface103] pim bsr-boundary
[SwitchC-Vlan-interface103] quit
[SwitchC] interface vlan-interface 104
[SwitchC-Vlan-interface104] pim bsr-boundary
[SwitchC-Vlan-interface104] quit
The configuration on Switch A, Switch B and Switch D is similar to the configuration on Switch C. The
specific configuration steps are omitted here.
3) Configure C-BSRs and C-RPs
# Configure Loopback 0 on Switch A as a C-BSR and a C-RP.
[SwitchA] pim
[SwitchA-pim] c-bsr loopback 0
[SwitchA-pim] c-rp loopback 0
