To view the RP information discovered on a device, use the display pim ipv6 rp-info command. For

example:
# View the RP information on Device A.

[DeviceA] display pim ipv6 rp-info

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 Device E as result of hash calculation, so an RPT will be built

between Device A and Device E. When the multicast source S (4001::100/64) registers with the RP, an

SPT will be built between Device D and Device E. Upon receiving IPv6 multicast data, Device A

immediately switches from the RPT to the SPT. Devices on the RPT path (Device A and Device E) have a

(*, G) entry, while devices on the SPT path (Device A and Device 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

devices. For example:
# View the IPv6 PIM multicast routing table information on Device A.

[DeviceA] display pim ipv6 routing-table

Total 1 (*, G) entry; 1 (S, G) entry

(*, FF0E::100)

RP: 1003::2
