# Configuring MLD Proxy

To configure a downstream interface, enable MLD on that interface. To configure MLD proxy on the router, complete the following tasks:

1. Enable IPv6 multicast.
2. Identify the interface that you want to act as the upstream interface.
3. Enable MLD proxy on that interface.
4. (Optional) Specify how often the router should send unsolicited reports to routers on the upstream interface.

| Note: You can configure MLD proxy only on IPv6 interfaces. For information about configuring IPv6 interfaces, see Configuring IPv6 in the JunosE IP, IPv6, and IGP Configuration Guide.

To configure MLD proxy on an interface:

1. Enable MLD proxy on the upstream interface.
   host1(config-if)#ipv6 mld-proxy

   Use the no version to disable MLD proxy on an interface.

   | Note: You can enable only one upstream interface.

2. (Optional) Configure unsolicited report interval, which specifies how often the upstream interface should transmit unsolicited reports.
   host1(config-if)#ipv6 mld-proxy unsolicited-report-interval 600

   Use the no version to transmit unsolicited reports using the default value, 100-tenths of a second (10 seconds).

   | Note: Issue this command only on the upstream interface. Otherwise, this command has no effect.

3. (Optional) Configure the MLD proxy version for the interface.
   host1(config-if)#ipv6 mld-proxy version 1

   Use the no version to set the version to its default value, MLDv2.
