multicast devices only. The switch listens to the MLD messages between multicast routers and
listeners, and maintains the multicast group forwarding list based on the listening result. The
switches forwards multicast packets according to the multicast forwarding list
The switch realizes the MLD Snooping function while supporting MLD v2. This way, the user
can acquire IPv6 multicast with the switch.

Command
Explanation
Global Mode

MLD snooping.
2. Configure MLD Snooping
Command
Explanation
Global Mode
ipv6 mld snooping vlan <vlan-id>
no ipv6 mld snooping vlan <vlan-id>
Enable MLD Snooping on specific VLAN. The
“no” form of this command disables MLD
Snooping on specific VLAN.
ipv6 mld snooping vlan <vlan-id> limit
{group <g_limit> | source <s_limit>}
no ipv6 mld snooping vlan <vlan-id> limit
Configure the number of the groups in which
the MLD Snooping can join, and the
maximum number of sources in each group.
The “no” form of this command restores to the
default.
ipv6 mld snooping vlan <vlan-id> l2-
general-querier
no ipv6 mld snooping vlan <vlan-id> l2-
general-querier
Set the VLAN level 2 general querier, which is
recommended on each segment. The “no”
form of this command cancels the level 2
general querier configuration.
ipv6 mld snooping vlan <vlan-id> mrouter-
port interface <interface –name>
no ipv6 mld snooping vlan <vlan-id>
mrouter-port interface <interface –name>
Configure the static mrouter port in specific
vlan. The “no” form of this command cancels
the mrouter port configuration.
ipv6 mld snooping vlan <vlan-id> mrouter-
port learnpim6
no ipv6 mld snooping vlan <vlan-id>
Enable the function that the specified VLAN
learns mrouter-port (according to pimv6
packets), the no command will disable the
