# Display IPv6 PIM information on Switch A.

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 IPv6 PIM multicast routing table information on Switch A.
[SwitchA] display pim ipv6 routing-table
Total 0 (*, G) entry; 1 (S, G) entry
