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.
Configure the SSM group range.

# Configure the SSM group range to be 232.1.1.0/24 on Switch A.

The configuration on Switch B, Switch C, Switch D and Switch E is similar to that on Switch A.
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

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. The
switches on the SPT path (Switch A and Switch D) have generated an (S, G) entry, but Switch E, which is
not on the SPT path, does not have multicast routing entries. 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
VPN-Instance: public net
Total 0 (*, G) entry; 1 (S, G) entry
