# Run the display pim neighbor command to check the PIM neighbor relation between the
S9300s. The display of the PIM neighbor relation S9300-D is as follows:
<S9300-D> display pim neighbor

# 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
Total 1 (*, G) entry; 1 (S, G) entry
(*, 225.1.1.1)
(10.110.5.100, 225.1.1.1)
<S9300-D> display pim routing-table
VPN-Instance: public net
Total 0 (*, G) entry; 1 (S, G) entry
(10.110.5.100, 225.1.1.1)
