MLDv1 is used to manage IPv6 multicast group members through the querying and response
mechanism. Based on MLDv1, MLDv2:

8.8.2 Preparing for configurations

Scenarios
Multicast arising in the IPv4 era solves the problem of single-point sending and multi-point
receiving, and transmits data efficiently point to multiple points on the network, thus saving
network bandwidth and lowering network load. It is enhanced on the IPv4 network. By
listening MLD messages and thus creating a forwarding table for multicast packets, the
ISCOM2600G-HI series switch can manage and control the forwarding of multicast packets,
and forward multicast packets to the target host.
Prerequisite
Configure the IPv6 address of the interface.

8.8.3 Default configurations of MLD

Default configurations of MLD are as below.
MLD ring network forwarding on the interface
MLD Snooping
MLD version
Aging time of MLD members
MLD robustness

8.8.4 Configuring basic functions of MLD

Configure basic functions of MLD for the ISCOM2600G-HI series switch as below.
MLDv2: defined by RFC3810, derived from IGMPv3
Additionally support filtering IPv6 multicast sources. When a host joins an IPv6
multicast group, it can request to receive or deny messages from a specified IPv6
multicast source.
Additionally support configuring the maximum response time. Thus, MLDv2 is
applicable to larger networks.
It does not support response suppression; in other words, the host does not need to
process packets from other hosts, thus simplifying hosts operations.
Add an S flag bit in the querying packet to enhance robustness of the system.
Add the retransmission mechanism to the querying and response packets.
