# 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.

ipv6 mld-proxy

- Use to enable MLD proxy on an interface.
- The interface for which you enable MLD proxy is the upstream interface.

  | Note: You can enable only one upstream interface.

- You can specify either MLD proxy version 1 or 2. The default is version 2.
- Example
  host1(config-if)#ipv6 mld-proxy
- Use the no version to disable MLD proxy on an interface.
- See ipv6 mld-proxy.

ipv6 mld-proxy unsolicited-report-interval

- Use to specify, in tenths of a second, how often the upstream interface should transmit unsolicited reports.

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

- Example
  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).
- See ipv6 mld-proxy unsolicited-report-interval

ipv6 mld-proxy version

- Use to set the MLD proxy version for the interface.
- Example
  host1(config-if)#ipv6 mld-proxy version 1
- Use the no version to set the version to its default value, MLDv2.
- See ipv6 mld-proxy version.
