To view the RP information discovered on a switch, use the display pim ipv6 rp-info command. For
example:
# View 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. Upon 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. Use the display pim ipv6 routing-table command to view the PIM routing table information on
the switches. For example:
# View the IPv6 PIM multicast routing table information on Switch A.
[SwitchA] display pim ipv6 routing-table
Total 1 (*, G) entry; 1 (S, G) entry
(*, FF0E::100)
