Assume that Host A needs to receive information addressed to IPv6 multicast group G (FF0E::100).
The RP corresponding to the multicast group G is Router E as result of hash calculation, so an RPT
will be built between Router A and Router E. When the multicast source S (4001::100/64)
registers with the RP, an SPT will be built between Router D and Router E. After receiving IPv6
multicast data, Router A immediately switches from the RPT to the SPT. The routers on the RPT path
(Router A and Router E) have a (*, G) entry, and the routers on the SPT path (Router A and Router
D) have an (S, G) entry. You can use the display pim ipv6 routing-table command to display the
PIM routing table information on the routers. For example:
# Display IPv6 PIM multicast routing table information on Router A.
[RouterA] display pim ipv6 routing-table
