[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
The configuration on Switch B and Switch C is similar to that on Switch A. The configuration on
Switch D and Switch E is also similar to that on Switch A except that it is not necessary to
enable IGMP on the corresponding interfaces on these two switches.
3) Configure the SSM group range
# Configure the SSM group range to be 232.1.1.0/24 one Switch A.
[SwitchA] acl number 2000
[SwitchA-acl-basic-2000] rule permit source 232.1.1.0 0.0.0.255
[SwitchA-acl-basic-2000] quit
[SwitchA] pim
[SwitchA-pim] ssm-policy 2000
[SwitchA-pim] quit
The configuration on Switch B, Switch C, Switch D and Switch E is similar to that on Switch A.
4) Verify the configuration
Carry out 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 A.
[SwitchA] display pim interface
Interface NbrCnt HelloInt DR-Pri DR-Address
Vlan100 0 30 1 10.110.1.1 (local)
Vlan101 1 30 1 192.168.1.2
Vlan102 1 30 1 192.168.9.2
Assume that Host A needs to receive the information a specific multicast source S
(10.110.5.100/24) sends to multicast group G (232.1.1.1). Switch A builds an SPT toward the
multicast source. Switches on the SPT path (Switch A and Switch D) have generated an (S, G)
entry, while Switch E, which is not on the SPT path, does not have multicast routing entries. You
can use the display pim routing-table command to view the PIM routing table information on
each switch. For example:
# View the PIM routing table information on Switch A.
[SwitchA] display pim routing-table
Total 0 (*, G) entry; 1 (S, G) entry
