1224 CHAPTER 73: MLD CONFIGURATIONConfiguring BasicFunctions of MLDConfigurationPrerequisitesBefore configuring the basic functions of MLD, complete the following tasks:■ Configure any IPv6 unicast routing protocol so that all devices in the domaincan be interoperable at the network layer.■ Configure IPv6 PIM-DM or IPv6 PIM-SM.In addition, prepare the following data:■ MLD version■ IPv6 multicast group address and IPv6 multicast source address for static groupmember configuration■ ACL rule for IPv6 multicast group filteringEnabling MLD Enable MLD on the interface on which IPv6 multicast group memberships are tobe created and maintained.Follow these steps to enable MLD:Configuring the MLDVersionBecause MLD message types and formats vary with MLD versions, the same MLDversion should be configured for all routers on the same subnet before MLD canwork properly.Configuring an MLD version globallyFollow these steps to configure an MLD version globally:Configuring an MLD version on an interfaceFollow these steps to configure an MLD version on an interface:To do...
