Assume that Host A needs to receive information addressed to IPv6 multicast group G (FF0E::101). Once
the IPv6 multicast source S (4001::100/64) sends IPv6 multicast packets to the IPv6 multicast group G, an
SPT is established through traffic flooding. Devices on the SPT path (Device A and Device D) have their
(S, G) entries. Host A sends an MLD report to Device A to join IPv6 multicast group G, and a (*, G) entry
is generated on Device A. To view the IPv6 PIM routing information on a device, use the display pim
ipv6 routing-table command. 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

The information on Device B and Device C is similar to that on Device A.
