Configuring Basic Mld Snooping Functions; Enabling Mld Snooping; Specifying The Version Of Mld Snooping - HP 6125G Configuration Manual

view is effective only if you do not make the same configuration in Layer 2 Ethernet interface view
or Layer 2 aggregate interface view.
For MLD snooping, the configurations that you make on a Layer 2 aggregate interface do not
•
interfere with those made on its member ports, nor do they participate in aggregation calculations.
Configurations that you make on a member port of the aggregate group will not take effect until the
port leaves the aggregate group.

Configuring basic MLD snooping functions

Before you configure basic MLD snooping functions, complete the following tasks:
• Enable IPv6 forwarding.
Configure the corresponding VLANs.
•
Determine the version of MLD snooping.
•

Enabling MLD snooping

When you enable MLD snooping, follow these guidelines:
• You must enable MLD snooping globally before you enable it for a VLAN.
After you enable MLD snooping for a VLAN, you cannot enable MLD or IPv6 PIM on the
•
corresponding VLAN interface, and vice versa.
MLD snooping for a VLAN works only on the ports in this VLAN.
•
To enable MLD snooping:
Step
1. Enter system view.
2. Enable MLD snooping
globally and enter
MLD-snooping view.
3. Return to system view.
4. Enter VLAN view.
5. Enable MLD snooping for the
VLAN.

Specifying the version of MLD snooping

Different versions of MLD snooping can process different versions of MLD messages:
• MLDv1 snooping can process MLDv1 messages, but flood MLDv2 messages in the VLAN instead
of processing them.
MLDv2 snooping can process MLDv1 and MLDv2 messages.
•
If you change MLDv2 snooping to MLDv1 snooping, the system:
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 MLDv1
•
snooping is changed back to MLDv2 snooping.
