MLD (Layer 3)
– 646 –
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.
