Configuration procedure
1 Configure the interface IP addresses and unicast routing protocol for each switch
Configure the IP address and subnet mask for each interface as per Figure 196.
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 among Switch A,
Switch B, Switch C and Switch D 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 on each interface
# Enable IP multicast routing on Switch A, enable PIM-DM on each interface, and
enable IGMPv2 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
