Configure Multicast routing on mesh end devices using the web-based GUI configurator.

This task allows you to set up Multicast routing to efficiently distribute data across mesh networks by defining Multicast groups, netmasks, and destination addresses.

Multicast routing enables efficient data distribution in mesh networks by sending data to multiple destinations simultaneously. This configuration is essential for optimizing network traffic and bandwidth usage in mesh topologies.

Before you begin

  • You can configure Multicast only on the mesh end device.

  • Ensure that you have a valid Multicast group, netmask, and destination IP addresses.

  • Ensure that you have a supported mesh end device to configure Multicast.

Follow these steps to configure Multicast using GUI:

Procedure

  1. Launch your computer's web browser and enter the URL to open the configurator login page.

  2. Enter your username and password in the respective Username and Enable Password fields.

  3. Click Login.

    Once you have successfully logged into the GUI, the URWB configurator appears.

  4. In the ADVANCED SETTINGS, click MULTICAST to open the MULTICAST window.

  5. In the Add a new MULTICAST route section, enter these details:

    • Multicast IP address in the MULTICAST Group field.

    • Netmask IP address in the Netmask field.

    • Destination IP address in the Destination Address field.

    Note

    The Destination Address field accepts the following special values:

    • 5.255.255.255 IP address in the Destination Address field sends the data to all the mesh point devices over the mesh network. This is applicable only for the downstream data flow.

    • 5.0.0.0 IP address in the Destination Address field sends the data to the current primary mesh end device. This is useful, especially when the mesh end's fast failover is enabled. This is applicable only for the upstream data flow.

    Tip

    The netmask field allows you to specify a block of Multicast addresses. When you specify multiple Multicast groups, the Multicast IP address should represent the network address for each group.

  6. Click add.

    Once you have successfully added a rule, the new Multicast route appears in the MULTICAST routes section.

    The configuration interface for MULTICAST settings displays the netmask field and options for specifying MULTICAST addresses, indicating successful application of the routing configuration.

  7. Click Apply to update the configuration.

    AP reboots to apply the changes.
