# Run the display pim ipv6 neighbor command to check the PIM neighbor relationship between
the S7700s. The display of the PIM-IPv6 neighbor relationship on SwitchA is as follows:

# Run the display pim ipv6 routing-table command to view the PIM-IPv6 multicast routing
table on an S7700. Assume that Host A joins multicast group G (FF0E::1). SwitchB generates
a (*, G) entry. When multicast source S (2001::5) sends multicast packets to G, a Shortest Path
Tree (SPT) is generated through flooding-prune. The (S, G) entry exists on each S7700 on the
network, and the display is as follows:
