Assume that Host A needs to receive the information a specific IPv6 multicast source S 4001::100/64
sends to IPv6 multicast group G FF3E::101. Switch A builds an SPT toward the IPv6 multicast
source. Switches on the SPT path (Switch A and Switch D) have generated an (S, G) entry, but
Switch E, which is not on the SPT path, does not have IPv6 multicast routing entries. You can use the
display pim ipv6 routing-table
command to view the IPv6 PIM routing table information on each
switch. For example:
# Display information about the IPv6 PIM multicast routing table on Switch A.
[SwitchA] display pim ipv6 routing-table
