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. Routers on the SPT path (Router A and
Router D) have their (S, G) entries. Host A sends an MLD report to Router A to join IPv6 multicast
group G, and a (*, G) entry is generated on Router A. To display the IPv6 PIM routing information
on a router, use the display pim ipv6 routing-table command. For example:
# Display IPv6 PIM multicast routing table information on Router A.
[RouterA] display pim ipv6 routing-table
