# Run the display pim routing-table command to view the PIM multicast routing table on the
S9300. Assume that HostA needs to receive the information about multicast group G
225.1.1.1/24. When sending multicast packets to multicast group G, multicast source S
10.110.5.100/24 generates an SPT through flooding and the (S, G) entries exist on S9300-A and
S9300-D that are in the SPT. When HostA joins multicast group G, an (*, G) entry is generated
on S9300-A. The information displayed on S9300-B and S9300-C is similar to the information
displayed on S9300-A. The displayed information is as follows:
<S9300-A> display pim routing-table
VPN-Instance: public net
