[SwitchB] display pim ipv6 rp-info

PIM-SM BSR RP information:
prefix/prefix length: FF0E::101:101/64

Assume that Host A needs to receive information addressed to the IPv6 multicast
group G (FF0E::101:101). An RPT will be built between Switch D and Switch B. A
(*, G) entry is created on Switch D and Switch B on the RPT path. Once the
multicast source S (2001::5/64) sends an IPv6 multicast packet to the IPv6
multicast group G, an (S, G) entry is created on the switches (Switch A and Switch
D) on the source tree. You can 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 0 (*, G) entry; 1 (S, G) entry
