Assume that Host A needs to receive the information addressed to a multicast group G 225.1.1.1. After the
multicast source S 10.1 10.5.100/24 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 Router A an IGMP report to join multicast group G, and a (*, G) entry is generated
on Router A. To view the PIM routing table information on a router, use the display pim routing-table
command. For example:
# Display the PIM routing table information on Router A.
[RouterA] display pim routing-table
