The configuration on Router B and Router C is similar to that on Router A. The
configuration on Router D and Router E is also similar to that on Router A except
that it is not necessary to enable IGMP on the corresponding interfaces on these
two routers.
3 Configure the range of PIM-SSM multicast group addresses
# Configure the range of PIM-SSM multicast group addresses 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

The configuration on Router B, Router C, Router D and Router E is similar to the
configuration on Router A.
4 Verify the configuration
Use the display pim interface command to view the PIM configuration and
running status on each interface. For example:
# Verify the PIM configuration information on Router A.
[RouterA] 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 (232.1.1.1/24). Router A builds an
SPT toward the multicast source. Routers on the SPT path (Router A and Router D
for example) generate (S, G) entries, while 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 view the PIM routing table information on each
router. For example:
# View the PIM routing table information on Router A.
