Specifying an MLD snooping version
About MLD snooping versions
Different MLD snooping versions can process different versions of MLD messages:
MLDv1 snooping can process MLDv1 messages and MLDv2 queries, but it floods MLDv2 reports in the VLAN or VSI instead of processing them.
MLDv2 snooping can process MLDv1 and MLDv2 messages.
Restrictions and guidelines
If you change the version of MLD snooping from 2 to 1, the system performs the following actions:
Clears all MLD snooping forwarding entries that are dynamically created.
Keeps static MLDv2 snooping forwarding entries (*, G).
Clears static MLDv2 snooping forwarding entries (S, G), which will be restored when MLD snooping is switched back to MLDv2 snooping.
For more information about static MLD snooping forwarding entries, see "Configuring a static member port."
