Configure the IP address and subnet mask for each interface as per
. The detailed
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
[SwitchA-pim] quit
