Step3 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 Device D.
[DeviceD] display pim interface

Carry out the display pim neighbor command to view the PIM neighboring relationships among the
devices. For example:
# Verify the PIM neighboring relationships on Device D.
[DeviceD] 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. The devices on the SPT path (Device A and Device D) have their (S,
G) entries. Host A sends an IGMP report to Device A to join the multicast group G, and a (*, G) entry is
