Drop Unknown
Enable or disable the function of dropping unknown IPv6 multicast packets.
Unknown IPv6 multicast data refers to IPv6 multicast data for which no entries
exist in the MLD snooping forwarding table.
• If the function of dropping unknown IPv6 multicast data is enabled, the switch
forwards the unknown IPv6 multicast packets to the router ports instead of
flooding them in the VLAN. If the switch does not have a router port, it drops
the unknown IPv6 multicast packets.
• If the function of dropping unknown IPv6 multicast data is disabled, the switch
floods the unknown IPv6 multicast data in the VLAN to which the unknown
IPv6 multicast data belong.
Querier
Enable or disable the MLD snooping querier function.
In an IPv6 multicast network that runs MLD, a Layer 3 device is elected as the MLD
querier to send MLD queries, so that all Layer 3 multicast devices can establish
and maintain IPv6 multicast forwarding entries, ensuring correct IPv6 multicast
traffic forwarding at the network layer.
On an IPv6 network without Layer 3 multicast devices, MLD querier cannot work
because a Layer 2 device does not support MLD. To address this issue, you can
enable MLD snooping querier on a Layer 2 device so that the device can
generate and maintain IPv6 multicast forwarding entries at data link layer for
correct IPv6 multicast traffic forwarding at data link layer.
