COMMAND USAGE
◆ MLDv1 is derived from IGMPv2, and MLDv2 from IGMPv3. IGMP uses IP
Protocol 2 message types, and MLD uses IP Protocol 58 message types,
which is a subset of the ICMPv6 messages.
◆ MLDv2 adds the ability for a node to report interest in listening to
packets with a particular multicast address only from specific source
addresses as required to support Source-Specific Multicast (SSM), or
from all sources except for specific source addresses.
◆ MLDv2 supports Source-Specific Multicast (SSM) which builds a reverse
tree from a host requesting a service back up to the multicast server.
◆ Multicast hosts on the subnet may support either MLD versions 1 or 2.
