• RFC 4605, Internet Group Management Protocol (IGMP)/Multicast Listener Discovery (MLD)-Based
Multicast Forwarding ("IGMP/MLD Proxying")
MLD configuration task list
Task Remarks
Configuring basic MLD functions
Enabling MLD Required.
Configuring the MLD version Optional.
Configuring static joining Optional.
Configuring an IPv6 multicast group filter Optional.
Setting the maximum number of IPv6 multicast
groups that an interface can join
Optional.
Adjusting MLD performance
Configuring Router-Alert option handling
methods
Optional.
Configuring MLD queries and response
parameters
Optional.
Configuring MLD fast-leave processing Optional.
Enabling the MLD host tracking function Optional.
Configuring MLD SSM mapping
Enabling MLD SSM mapping Optional.
Configuring MLD SSM mappings Optional.
Configuring MLD proxying
Enabling MLD proxying Optional.
Configuring IPv6 multicast forwarding on a
downstream interface
Optional.
For the configuration tasks described in this section:
• In MLD view, the configuration takes effect globally. In interface view, the configuration takes effect
on only the current interface.
• If no configuration is performed in interface view, the global configuration in MLD view will apply
to that interface. Configurations performed in interface view take precedence over those performed
in MLD view.
Configuring basic MLD functions
Before you configure basic MLD functions, complete the following tasks:
• Enable IPv6 forwarding and configure an IPv6 unicast routing protocol so that all devices in the
domain can be interoperable at the network layer.
• Configure IPv6 PIM-DM or IPv6 PIM-SM.
• Determine the MLD version.
• Determine the IPv6 multicast group address and IPv6 multicast source address for static group
member configuration.
• Determine the ACL rule for IPv6 multicast group filtering.
• Determine the maximum number of IPv6 multicast groups that an interface can join.
