Assume that Host A needs to receive information addressed to the IPv6 multicast group G (FF0E::100).
The RP corresponding to the multicast group G is Switch E as a result of hash calculation, so an RPT
will be built between Switch A and Switch E. When the IPv6 multicast source S (4001::100/64) registers
with the RP, an SPT will be built between Switch D and Switch E.
Upon receiving IPv6 multicast data,
Switch A immediately switches from the RPT to the SPT. Switches on the RPT path (Switch A and
Switch E) have a (*, G) entry, while switches on the SPT path (Switch A and Switch 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 switches. For example:
# View the IPv6 PIM multicast routing table information on Switch A.
[SwitchA] display pim ipv6 routing-table
Total 1 (*, G) entry; 1 (S, G) entry
