Enabling MLD
Enable MLD on the interface on which IPv6 multicast group memberships will be created and
maintained.
To enable MLD:
Step Command Remarks
1. Enter system view. system-view N/A
2. Enable IPv6 multicast
routing.
multicast ipv6 routing-enable Disable by default.
3. Enter interface view. interface interface-type interface-number N/A
4. Enable MLD. mld enable Disabled by default.
Configuring the MLD version
Because MLD message types and formats vary with MLD versions, the same MLD version should be
configured for all routers on the same subnet before MLD can operate correctly.
Configuring an MLD version globally
Step Command Remarks
1. Enter system view. system-view N/A
2. Enter MLD view. mld N/A
3. Configure an MLD version
globally.
version version-number MLDv1 by default.
Configuring an MLD version on an interface
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 static joining
After an interface is configured as a static member of an IPv6 multicast group or an IPv6 multicast source
and group, it will act as a virtual member of the IPv6 multicast group to receive IPv6 multicast data
addressed to that IPv6 multicast group for the purpose of testing IPv6 multicast data forwarding.
Configuration guidelines
• Before you can configure an interface of an IPv6 PIM-SM device as a static member of an IPv6
multicast group or an IPv6 multicast source and group, if the interface is MLD and IPv6 PIM-SM
enabled, it must be an IPv6 PIM-SM DR. If this interface is MLD enabled but not IPv6 PIM-SM
