MLD and VLAN configuration

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
