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