Assume that Host A needs to receive information addressed to the multicast group G 225.1.1.0. The RP
corresponding to the multicast group G is Switch E as a result of hash calculation, so an RPT will be built
between Switch A and Switch E. When the multicast source S 10.110.5.100/24 registers with the RP, an
SPT will be built between Switch D and Switch E. After receiving multicast data, Switch A immediately
switches from the RPT to the SPT. Switches on the RPT path (Switch A and Switch E) have a (*, G) entry,
and switches on the SPT path (Switch A and Switch D) have an (S, G) entry. You can use the display pim
routing-table command to view the PIM routing table information on the switches. For example:
# Display PIM routing table information on Switch A.
[SwitchA] display pim routing-table
VPN-Instance: public net
Total 1 (*, G) entry; 1 (S, G) entry
