Configure the IP address and subnet mask for each interface as per
. Detailed
configuration steps are omitted here.
Configure the OSPF protocol for interoperation among the switches in the PIM-DM domain.
Ensure the network-layer interoperation in the PIM-DM domain and enable dynamic update of
routing information among the switches through a unicast routing protocol. Detailed
configuration steps are omitted here.
2) Enable IP multicast routing, and enable PIM-DM and IGMP
# Enable IP multicast routing on Switch A, enable PIM-DM on each interface, and enable IGMP
on VLAN-interface 100, which connects Switch A to the stub network.
<SwitchA> system-view
[SwitchA] multicast routing-enable
[SwitchA] interface vlan-interface 100
[SwitchA-Vlan-interface100] igmp enable
[SwitchA-Vlan-interface100] pim dm
[SwitchA-Vlan-interface100] quit
[SwitchA] interface vlan-interface 103
[SwitchA-Vlan-interface103] pim dm
[SwitchA-Vlan-interface103] quit
The configuration on Switch B and Switch C is similar to that on Switch A.
# Enable IP multicast routing on Switch D, and enable PIM-DM on each interface.
<SwitchD> system-view
[SwitchD] multicast routing-enable
[SwitchD] interface vlan-interface 300
[SwitchD-Vlan-interface300] pim dm
[SwitchD-Vlan-interface300] quit
[SwitchD] interface vlan-interface 103
[SwitchD-Vlan-interface103] pim dm
[SwitchD-Vlan-interface103] quit
[SwitchD] interface vlan-interface 101
[SwitchD-Vlan-interface101] pim dm
[SwitchD-Vlan-interface101] quit
[SwitchD] interface vlan-interface 102
[SwitchD-Vlan-interface102] pim dm
[SwitchD-Vlan-interface102] quit
3) Verify
the
configuration
Use the display pim interface command to view the PIM configuration and running status on
each interface. For example:
# View the PIM configuration information on Switch D.
[SwitchD] display pim interface
Interface NbrCnt HelloInt DR-Pri DR-Address
Vlan300 0 30 1 10.110.5.1 (local)
Vlan103 1 30 1 192.168.1.2 (local)
Vlan101 1 30 1 192.168.2.2 (local)
Vlan102 1 30 1 192.168.3.2 (local)
Carry out the display pim neighbor command to view the PIM neighboring relationships
among the switches. For example:
# View the PIM neighboring relationships on Switch D.
