Hello,
MLD manages IPv6 multicast members. MLD sets up and maintains member relationships between IPv6 hosts and the multicast router to which the hosts are directly connected.
MLD has two versions: MLDv1 and MLDv2. Both MLD versions support the ASM model. MLDv2 supports the SSM model independently, while MLDv1 needs to work with SSM mapping to support the SSM model.
MLD applies to IPv6 and provides the similar functions as the IGMP for IPv4. MLDv1 is similar to IGMPv2, and MLDv2 is similar to IGMPv3.
Some features of MLD and IGMP are implemented in the same manner.
More details about MLD, please refer to
