To view the RP information discovered on a switch, use the display pim ipv6 rp-info command. For
example:
# Display the RP information on Switch A.
[SwitchA] display pim ipv6 rp-info

Assume that Host A needs to receive information addressed to the IPv6 multicast group G
FF0E::100. 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 IPv6 multicast source
S 4001::100/64 registers with the RP, an SPT will be built between Switch D and Switch E. After
receiving IPv6 multicast data, Switch A immediately switches from the RPT to the SPT. The switches
on the RPT path (Switch A and Switch E) have a (*, G) entry, and the switches on the SPT path
(Switch A and Switch D) have an (S, G) entry. You can use the display pim ipv6 routing-table
command to view the PIM routing table information on the switches. For example:
