[RouterA-Ethernet1/1] quit
[RouterA] interface ethernet 1/2
[RouterA-Ethernet1/2] pim sm

# Enable IP multicast routing, IGMP, and PIM-SM on Router B and Router C in the same way Router
A is configured. (Details not shown.)
# Enable IP multicast routing and PIM-SM on Router D and Router E in the same way Router A is
configured. (Details not shown.)
4. Configure the SSM group range:
# Configure the SSM group range to be 232.1.1.0/24 on Router A.
[RouterA] acl number 2000
[RouterA-acl-basic-2000] rule permit source 232.1.1.0 0.0.0.255
[RouterA-acl-basic-2000] quit
[RouterA] pim
[RouterA-pim] ssm-policy 2000
[RouterA-pim] quit
# Configure the SSM group range on Router B, Router C, Router D and Router E in the same way
Router A is configured. (Details not shown.)
Verifying the configuration
Use the display pim interface command to display the PIM information on each interface. For example:
# Display PIM configuration information on Router A.
[RouterA] display pim interface
Interface NbrCnt HelloInt DR-Pri DR-Address
Eth1/1 0 30 1 10.110.1.1 (local)
Eth1/2 1 30 1 192.168.1.2
Eth1/3 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). Router A builds an SPT toward the multicast source. Routers on the
SPT path (Router A and Router D) have generated (S, G) entry, but Router E, which is not on the SPT path,
does not have multicast routing entries. You can use the display pim routing-table command to display
the PIM routing table information on each router. For example:
# Display PIM routing table information on Router A.
[RouterA] display pim routing-table
Total 0 (*, G) entry; 1 (S, G) entry
