Static and Dynamic MLD Interfaces

The router supports static and dynamic Multicast Listener Discovery (MLD) interfaces. Unlike static interfaces, dynamic interfaces are not restored when you reboot the router. For some protocols, dynamic layers can build on static layers in an interface; however, in a dynamic MLD interface, all the layers are dynamic. See Figure 19 for examples of static and dynamic MLD interfaces.

Static and Dynamic MLD Interfaces

Static MLD interfaces are configured with software such as the command-line interface (CLI) or an SNMP application; dynamic MLD interfaces are configured with a profile. A profile comprises a set of attributes for an interface; a profile for dynamic MLD interfaces contains attributes for configuring all the layers in the interface.

You define a profile by using the same CLI commands that you use to configure a static MLD interface; however, the mode in which you use the commands differs. Use the commands in Interface Configuration mode to configure a static MLD interface and in Profile Configuration mode to define a profile.

When you have defined a profile, you can apply it to an interface or a group of interfaces. Profiles provide an efficient method of creating and managing large numbers of dynamic interfaces. For detailed information about creating and assigning profiles, see Configuring Dynamic Interfaces in the JunosE Link Layer Configuration Guide. When you create a profile for dynamic MLD interfaces, specify attributes for configuring all layers in the interface.

You use the MLD commands shown in Table 65 to configure a static MLD interface. You also use these commands to define the attributes for the MLD layer when you create a profile for dynamic MLD interfaces.

You can also use various MLD-specific RADIUS attributes in RADIUS Access-Accept messages as an alternative method of configuring certain values. See Juniper Networks VSAs Supported for Subscriber AAA Access Messages for additional information.
