ProSafe 7000 Managed Switch Software Administration Manual, Release 8.0.3 Chapter 29 MLD In this chapter, the following examples are provided: • "Configure MLD" on page 32-2 • "MLD Snooping" on page 32-5 Multicast Listener Discovery (MLD) protocol enables IPv6 routers to discover the presence of multicast listeners, the nodes who wish to receive the multicast data packets, on its directly-attached interfaces. The protocol specifically discovers which multicast addresses are of interest to its neighboring nodes and provides this information to the active multicast routing protocol that makes decisions on the flow of multicast data packets. The Multicast router sends General Queries periodically to request multicast address listeners information from systems on an attached network. These queries are used to build and refresh the multicast address listener state on attached networks. Multicast listeners respond to these queries by reporting their multicast addresses listener state and their desired set of sources with Current-State Multicast address Records in the MLD2 Membership Reports. The Multicast router also processes unsolicited FilterMode-Change records and Source-List-Change Records from systems that want to indicate interest in receiving or not receiving traffic from particular sources. Configure MLD In this case, PIM-DM is enabled on Switch A and B, and MLD is enabled on Switch B's 1/0/24 to discover the multicast listeners. 29-1 v1.0, June 2010 MLD
