Configuring IP Multicast Switching
IPMSv6 Overview
An IPv6 multicast address identifies a group of nodes. A node can belong to any number of multicast
groups. IPv6 multicast addresses are classified as fixed scope multicast addresses and variable scope
multicast addresses.(See the
IPMSv6 tracks the source VLAN on which the Multicast Listener Discovery Protocol (MLD) requests are
received. The network interfaces verify that a multicast packet is received by the switch on the source (or
expected) port.
IPMSv6 Example
The figure on the following page shows an IPMSv6 network where video content can be provided to
clients that request it. A server is attached to the switch that provides the source (i.e, multicast) IPv6
addresses. Clients from two different attached networks send MLD reports to the switch to receive the
video content.
