d. Verifying the configuration
Use the display pim interface command to display PIM information on each interface. For
example:
# Display PIM information on the firewall.
[Firewall] display pim interface

Use the display pim neighbor command to display PIM neighboring relationship among the
routers. For example:
# Display PIM neighboring relationship on the firewall.
[Firewall] 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. Router A and the firewall on
the SPT path 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 the display pim
routing-table command to display PIM routing table information on each router. For example:
# Display PIM routing table information on Router A.
[RouterA] display pim routing-table
