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 and the firewall on the SPT path (Router A
and Firewall) 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 routers and the firewall. For
example:
# Display the PIM routing table information on Router A.
[RouterA] display pim routing-table
