MLD and VLAN configuration
You can configure MLD snooping on some VLANs or all VLANs. Each VLAN can be independently
enabled or disabled for MLD snooping, or can be configured with MLDv1 or MLDv2. In general, the
IPv6 MLD snooping commands apply globally to all VLANs except those configured with VLAN-
specific MLD snooping commands. VLAN-specific MLD snooping commands supersede global IPv6
MLD snooping commands.
MLDv1 with MLDv2
MLD snooping can be configured as MLDv1 or MLDv2 on individual ports on a VLAN. An interface or
router sends queries and reports that include the MLD version with which it has been configured. The
version configuration applies only to the sending of queries. The snooping device recognizes and
processes MLDv1 and MLDv2 packets regardless of the version configured.
NOTE
To avoid version deadlock, when an interface receives a report with a lower version than that for which
it has been configured, the interface does not automatically downgrade the running MLD version.
MLD snooping configuration
Configuring Multicast Listening Discovery (MLD) snooping on an IPv6 device consists of the following
global and VLAN-specific tasks.
MLD snooping global tasks
Configuring hardware and software resource limits
Disabling transmission and receipt of MLD packets on a port
Configuring the MLD mode: active or passive (must be enabled for MLD snooping)
Modifying the age interval
Modifying the interval for query messages (active MLD mode only)
Specifying the global MLD version
Enabling and disabling report control (rate limiting)
Modifying the leave wait time
Modifying the mcache age interval
Disabling error and warning messages
MLD snooping VLAN-specific tasks:
Configuring the MLD mode for the VLAN: active or passive
Enabling or disabling MLD snooping for the VLAN
Configuring the MLD version for the VLAN
Configuring the MLD version for individual ports
Configuring static groups
Configuring static router ports
Disabling proxy activity for a static group
Enabling client tracking and the fast leave feature for MLDv2
Configuring fast leave for MLDv1
Configuring fast-convergence
