Assume that Host A needs to receive the information addressed to multicast group 225.1.1.1. After
multicast source 10.1 10.5.100/24 sends multicast packets to the multicast group, an SPT is established
through traffic flooding. Switches on the SPT path (Switch A and Switch D) have their (S, G) entries. Host
A sends an IGMP report to Switch A to join the multicast group G, and a (*, G) entry is generated on
Switch A. You can use the display pim routing-table command to display the PIM routing table
information on each switch. For example:
# Display the PIM routing table information on Switch A.
[SwitchA] display pim routing-table
