Configuring IP Multicast Switching

IPMSv6 Overview

OmniSwitch AOS Release 6 Network Configuration Guide

page 42-23

The Internet Assigned Numbers Authority (IANA) classified the scope for IPv6 multicast addresses as 
fixed scope multicast addresses and variable scope multicast addresses. However, as the table below 
shows only well-known addresses, which are reserved and cannot be assigned to any multicast group.

MLD is used by IPv6 systems (hosts and routers) to report their IPv6 multicast group memberships to any 
neighboring multicast routers. MLD Version 1 (MLDv1) handles forwarding by IPv6 multicast destina-
tion addresses only. MLD Version 2 (MLDv2) handles forwarding by source IPv6 addresses and IPv6 
multicast destination addresses. Both MLDv1 and MLDv2 are supported.

Note. See 

 for information on configuring the IGMP 

version.

MLDv2 uses source filtering and reports multicast memberships to neighboring routers by sending 
membership reports. MLDv2 also supports Source Specific Multicast (SSM) by allowing hosts to report 
interest in receiving packets only from specific source addresses or from all but specific source addresses.
