The configuration on Router B and Router C is similar to that on Router A.

Carry out display pim interface to view the PIM configuration and running status on each interface. For
example:
# View the PIM configuration information on Router D.
[RouterD] display pim interface

Carry out display pim neighbor to view the PIM neighboring relationships among the routers. For
example:
# Verify the PIM neighboring relationships on Router D.
[RouterD] display pim neighbor

Assume that Host A needs to receive the information addressed to multicast group G (225.1.1.1). After
the multicast source S (10.110.5.100/24) sends multicast packets to the multicast group G, an SPT is
established through traffic flooding. Routers on the SPT path (Router A and Router D) have their (S, G)
entries. Host A sends an IGMP report to Router A to join the multicast group G, and a (*, G) entry is
generated on Router A. You can use display pim routing-table to view the PIM routing table information
on each router. For example:
