Assume that Host A needs to receive the information addressed to IPv6 multicast group FF0E::101. After
IPv6 multicast source 4001::100/64 sends IPv6 multicast packets to the IPv6 multicast group, an SPT is
established through traffic flooding. Switches on the SPT path (Switch A and Switch D) have their (S, G)
entries. Host A sends an MLD report to Switch A to join IPv6 multicast group, and a (*, G) entry is
generated on Switch A. You can use the display ipv6 pim routing-table command to display the IPv6 PIM
routing table information on each switch. For example:
