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 10 on page 179 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.

The following sections describe the tasks associated with these and other ipv6 mld
commands.
You can also use various MLD-specific RADIUS attributes in RADIUS Access-Accept
messages as an alternative method of configuring certain values. See Configuring RADIUS
Attributes in the JunosE Broadband Access Configuration Guide for additional information.
Enabling MLD on an Interface
You must start MLD on each interface that you want to use the protocol. You can configure
MLD and PIM on the same interface. If you configure only MLD on an interface, the router
determines that MLD owns that interface. If you configure MLD and PIM on an interface,
the router determines that PIM owns the interface.
In an MLDv1 or MLDv2 network, the querier is the router with the lowest IPv6 address.
To start MLD, complete the following steps:
