Configuring Mld Snooping Basic Functions - HP A8800 Configuration Manual

Configuring MLD snooping basic functions

Before configuring the basic functions of MLD snooping, 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 and/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 does the following:
Clears all MLD snooping forwarding entries that are dynamically created, and also does the
•
following:
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
To specify the version of MLD snooping:
