Configuring Multicast Listener Discovery

You can enable the IPv6 multicast snooping on themanaged deviceby using the WebUI orCLICommand-Line Interface. A console interface with a command line shell that allows users to execute text input as commands and convert these commands to appropriate functions.and configureMLDMulticast Listener Discovery. A component of the IPv6 suite. It is used by IPv6 routers for discovering multicast listeners on a directly attached link.parameters such as query interval, query response interval, robustness variable, and ssm-range.

The Source Specific Multicast (SSM) supports delivery of multicast packets that originate only from a specific source address requested by the receiver. You can forward multicast streams to the clients if the source and group match the client subscribed source group pairs (S,G).

Themanaged devicesupports the following IPv6 multicast source filtering modes:

Include - In Include mode, the reception of packets sent to a specified multicast address is enabled only from the source addresses listed in the source list. The default IPv6 SSM address range is FF3X::4000:1 – FF3X::FFFF:FFFF, and the hosts subscribing to SSM groups can only be in the Include mode.

排除在Exclude mode, the reception of packets sent to a specific multicast address is enabled from all source addresses. If there is a client in the Exclude mode, thesubscriptionA business model where a customer pays a certain amount as subscription price to obtain access to a product or service.is treated as an MLDv1 join.

MLDMulticast Listener Discovery. A component of the IPv6 suite. It is used by IPv6 routers for discovering multicast listeners on a directly attached link.snooping does not add IPv6 Solicited-Node multicast address or groups to the multicast table. A Solicited-Node multicast address is an IPv6 multicast address valid within the local-link (example, anEthernetEthernet is a network protocol for data transmission over LAN.segment or a Frame Relay cloud). Every IPv6 host has at least one such address per interface. Solicited-Node multicast addresses are used in Neighbor Discovery Protocol for obtaining the layer 2 link-layer addresses of other nodes.

1.In theManaged Networknode hierarchy, navigate to theConfiguration > Interfaces >VLANstab.

2.Click aVLANVirtual Local Area Network. In computer networking, a single Layer 2 network may be partitioned to create multiple distinct broadcast domains, which are mutually isolated so that packets can only pass between them through one or more routers; such a domain is referred to as a Virtual Local Area Network, Virtual LAN, or VLAN.name underVLANsand click the correspondingVLANVirtual Local Area Network.

When you enter the SSM range ensure that the upstream router has the same range, else the multicast stream would be dropped.
