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:

1. Enable MLD on the interface (MLDv2 is the default version).
2. (MLDv1) Specify the MLD version for the interface.

ipv6 mld

• Use to enable MLD on an interface and to set the MLD version to MLDv2. Use the ipv6 mld version command to specify a different MLD version.
• Example

  host1:boston(config-if)#ipv6 mld

• Use the no version to disable MLD on an interface.
• See ipv6 mld.

ipv6 mld version

• Use to set the MLD version (1 or 2) for the interface.
• Example

  host1:boston(config-if)#ipv6 mld version 2

• Use the no version to set the version to the default, MLDv2.
• See ipv6 mld version.
