(namely ff02::1). Once there is a listener who wishes to join the multicast address, it will send a MLD Multicast
listener Report back through the multicast address.
MLD Snooping is namely the MLD listening. The switch restricts the multicast traffic from flooding through
MLD Snooping, and forward the multicast traffic to ports associated to 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.
49.7.2 MLD Snooping Configuration Task
1. Enable the MLD Snooping function
2. Configure the MLD Snooping
1. Enable the MLD Snooping function
Command Explanation
Global Mode
ipv6 mld snooping
no ipv6 mld snooping
Enable global MLD Snooping, the “no ipv6
mld snooping” command disables the
global 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>
Configure the static mrouter port in specific
vlan. The “no” form of this command cancels
the mrouter port configuration.
