Implementing IPv6 Multicast
Traditional IP communication allows a host to send packets to a single host (unicast transmission) or to
all hosts (broadcast transmission). IPv6 multicast provides a third scheme, allowing a host to send a
single data stream to a subset of all hosts (group transmission) simultaneously.
This document provides information on how to implement IPv6 multicast. For the command reference,
refer to the Cisco IOS IPv6 Command Reference.

IPv6 Multicast Overview
An IPv6 multicast group is an arbitrary group of receivers that want to receive a particular data stream.
This group has no physical or geographical boundaries--receivers can be located anywhere on the
Internet or in any private network. Receivers that are interested in receiving data flowing to a particular
group must join the group by signaling their local switch. This signaling is achieved with the MLD
protocol.
Switches use the MLD protocol to learn whether members of a group are present on their directly
attached subnets. Hosts join multicast groups by sending MLD report messages. The network then
delivers data to a potentially unlimited number of receivers, using only one copy of the multicast data
on each subnet. IPv6 hosts that wish to receive the traffic are known as group members.
