• Determine the ACL rule for IPv6 multicast group filtering.
Enabling MLD
Enable MLD on the interface on which IPv6 multicast group memberships are created and maintained.
To enable MLD:
Step Command Remarks
1. Enter system view. system-view N/A
2. Enable IPv6 multicast
routing and enter IPv6 MRIB
view.
ipv6 multicast routing [ vpn-instance
vpn-instance-name ]
Disable by default.
3. Return to system view. quit N/A
4. Enter interface view. interface interface-type interface-number N/A
5. Enable MLD. mld enable Disabled by default.
Specifying the MLD version
Because MLD message types and formats vary with MLD versions, configure the same MLD version for all
routers on the same subnet. Otherwise, MLD cannot operate correctly.
To specify an MLD version:
Step Command Remarks
1. Enter system view. system-view N/A
2. Enter interface view.
interface interface-type
interface-number
N/A
3. Configure an MLD version on
the interface.
mld version version-number MLDv1 by default.
Configuring an interface as a static member interface
You can configure an interface as a static member of an IPv6 multicast group or an IPv6 multicast source
and group, so that the interface can receive IPv6 multicast data addressed to that IPv6 multicast group for
the purpose of testing IPv6 multicast data forwarding.
Configuration guidelines
• An MLD-enabled static member interface has the following restrictions:
{
If it is enabled with IPv6 PIM-SM, it must be an IPv6 PIM-SM DR.
{
If it is not enabled with IPv6 PIM-SM, it must be an MLD querier.
For more information about IPv6 PIM-SM and DR, see " Configuring IPv6 PIM ."
• A static member interface does not respond to queries from the MLD querier. When you configure
an interface as a static member interface or cancel this configuration on the interface, the interface
