NOTE:
If no static router port is configured, IPv6 multicast transmission is interrupted for a while after the path of
Switch A—Switch B—Switch C is blocked. The reason is that at least one MLD query/response exchange
is required before the new path can forward IPv6 multicast packets.
For more information about the STP, see Layer 2—LAN Switching Configuration Guide.
