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 Firewall C as result of hash calculation, so an RPT
will be built between Firewall A and Firewall C. When the multicast source S (4001::100/64)
registers with the RP, an SPT will be built between Firewall B and Firewall C. After receiving IPv6
multicast data, Firewall A immediately switches from the RPT to the SPT. The firewalls on the RPT
path (Firewall A and Firewall C) have a (*, G) entry, and the firewalls on the SPT path (Firewall A
and Firewall B) have an (S, G) entry. You can use the display pim ipv6 routing-table command to
display PIM routing table information on the firewalls. For example:
# Display IPv6 PIM multicast routing table information on Firewall A.
[FirewallA] display pim ipv6 routing-table
Total 1 (*, G) entry; 1 (S, G) entry
(*, FF0E::100)
