Configuring the version of MLD snooping

By configuring the MLD snooping version, you actually configure the version of MLD messages that MLD

snooping can process.

• MLD snooping version 1 can process MLDv1 messages, but cannot analyze and process MLDv2

messages, which will be flooded in the VLAN.

• MLD snooping version 2 can process MLDv1 and MLDv2 messages.

Follow these steps to configure the version of MLD snooping:

To do… Use the command… Remarks

Enter system view system-view —

Enter VLAN view vlan vlan-id —

Configure the version of MLD

snooping

mld-snooping version

version-number

Optional

Version 1 by default

CAUTION:

If you switch MLD snooping from version 2 to version 1, the system will clear all MLD snooping forwardin

entries from dynamic joining, and will:

• Keep forwarding entries from version 2 static (*, G) joining

• Clear forwarding entries from version 2 static (S, G) joining, which will be restored when MLD snoopin

is switched back to version 2

For more information about static joining, see “Configuring static ports.”

Configuring IPv6 static multicast MAC address entries

In Layer-2 multicast, a Layer-2 IPv6 multicast protocol—such as MLD snooping—can dynamically add

IPv6 multicast MAC address entries. You can also configure IPv6 multicast MAC address entries.

Configuring an IPv6 static multicast MAC address entry in system view

Table 10 Configure an IPv6 static multicast MAC address entry in system view

To do... Use the command... Remarks

Enter system view system-view —

Configure a static multicast MAC

address entry

mac-address multicast mac-address

interface interface-list vlan vlan-id

Required

No static multicast MAC address

entries exist by default.

Configuring an IPv6 static multicast MAC address entry in interface view
