• RFC 4605, Internet Group Management Protocol (IGMP)/Multicast Listener Discovery (MLD)-Based
Multicast Forwarding (“IGMP/MLD Proxying”)
MLD configuration task list
Complete these tasks to configure MLD:
Task Remarks
Configuring basic functions of MLD
Enabling MLD Required
Configuring the MLD version Option
Configuring static joining Optional
Configuring an ipv6 multicast group filter Optional
Configuring the maximum number of IPv6
multicast groups that an interface can join
Optional
Adjusting MLD performance
Configuring MLD message options Optional
Configuring MLD query and response
parameters
Optional
Configuring MLD fast leave processing 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
NOTE:
In MLD view, the configuration is globally effective. In interface view, the configuration is effective on
the current interface only.
If no configuration is performed in interface view, the global configurations performed in MLD view
will apply to that interface. Configurations performed in interface view take precedence over those
performed in MLD view.
Configuring basic functions of MLD
Configuration prerequisites
Before you configure the basic functions of MLD, complete the following tasks:
• Configure any 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
