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 and the firewall on the
SPT path (Router A and Firewall) 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 routers and the firewall, use the display pim ipv6 routing-table
command. For example:
# Display the IPv6 PIM multicast routing table information on Router A.
[RouterA] display pim ipv6 routing-table
