Managing multicast interfaces

You can view the table of multicast interfaces in a CPE template and on a CPE device:

  • To display the table of multicast interfaces in a CPE template, go to the SD-WAN → CPE templates menu section, click the CPE template, and select the Multicast → Interfaces tab.
  • To display the table of multicast interfaces on a CPE device, go to the SD-WAN → CPE menu section, click the CPE device, and select the Multicast → Interfaces tab.

Information about multicast interfaces is displayed in the following columns of the table:

  • Network interface is the network interface used as a multicast interface.
  • PIM indicates whether the exchange of messages with peers via the PIM protocol is enabled on the multicast interface:
    • Enabled
    • Disabled
  • IGMP indicates whether the exchange of messages with peers via the IGMP protocol is enabled on the multicast interface:
    • Enabled
    • Disabled
  • DR priority is the priority of the multicast interface. The highest-priority multicast interface becomes the designated router of the LAN segment. The greater the value, the higher the priority of the multicast interface.
  • Inherited indicates whether the multicast interface is inherited from CPE template:
    • Yes
    • No

    This column is displayed only on the CPE device.

  • Management contains the actions that can be performed with the multicast interface.

Creating a multicast interface

You can create a multicast interface in a CPE template or on an individual device. A multicast interface created in the CPE template is automatically created on all CPE devices that use this CPE template.

To create a multicast interface:

  1. Create a multicast interface in one of the following ways:
    • If you want to create a multicast interface in a CPE template, go to the SD-WAN → CPE templates menu section, click the CPE template, and select the Multicast → Interfaces tab.
    • If you want to create a multicast interface on a CPE device, go to the SD-WAN → CPE menu section, click the CPE device, select the Multicast → Interfaces tab, and select the Override check box.

    A table of multicast interfaces is displayed.

  2. Click + Multicast interface.
  3. This opens a window, in that window, in the Network interface drop-down list, select a created network interface which you want to use as a multicast interface.
  4. Configure the PIM protocol on the multicast interface:
    1. In the PIM drop-down list, select Enabled. The default value is Disabled.
    2. If you want to switch the multicast interface to passive mode, select the Passive check box. In passive mode, multicast interfaces do not exchange control packets. This check box is cleared by default.
    3. If you want to prohibit the exchange of bootstrap packets on the multicast interface, clear the BSM check box. This check box is selected by default.
    4. If you want to prohibit the exchange of unicast bootstrap packets on the multicast interface, clear the Unicast BSM check box. This check box is selected by default.
    5. In the DR priority field, enter the priority of the multicast interface. The highest-priority multicast interface becomes the designated router of the LAN segment. The greater the value, the higher the priority of the multicast interface. Range of values: 1 to 4,294,967,295. Default value: 1.
    6. In the Hello (sec.) field, enter the time interval in seconds that the multicast interface uses to send control packets to PIM neighbors. Range of values: 1 to 180. Default value: 30.
    7. In the Hold (sec.) field, enter the time interval in seconds that the multicast interface uses to receive control packets from PIM neighbors. If no control packets are received from a PIM neighbor within the specified time, the PIM interface considers this PIM neighbor unavailable. Range of values: 1 to 630. Default value: 105.
    8. If multiple IP addresses are assigned to a multicast interface and you want to use the specified IPv4 source address when sending PIM messages, enter the IPv4 address in the Source IP field.
  5. Configure the IGMP protocol on the multicast interface:
    1. In the IGMP drop-down list, select Enabled. The default value is Disabled.
    2. In the Version drop-down list, select the version of the IGMP protocol on the multicast interface:
      • 2
      • 3. This is the default setting.
    3. In the Query interval (sec.) field, enter the time interval in seconds for sending queries from the multicast interface to clients. Queries are used to determine if multicast traffic needs to be sent to clients. Range of values: 1 to 250. Default value: 125.
    4. In the Query response time (sec.) field, enter the time in seconds that the multicast interface must wait to receive responses from clients. If no response to a query is received from the client within the specified time, the multicast interface does not send traffic packets. Range of values: 1 to 125. Default value: 10.
    5. If you want to specify multicast groups:
      1. Under Join group, click + Add and enter the IPv4 address of the multicast group.
      2. If you want to connect the multicast interface to the specified source of the multicast group, under Source address, enter the IPv4 address of the source.

      The multicast group is specified and displayed in the Join group and Source address sections. You can specify multiple multicast groups or delete multicast groups. To delete a multicast group, click the delete icon cross_icon_3 next to it.

      You need to specify multicast groups in one of the following cases:

      • The network segment has permanent clients to which you need to send traffic packets from a multicast group in a quick and stable way.
      • The network segment does not contain clients or hosts in the segment cannot send report messages, but traffic packets from a multicast group must be sent to this segment.
  6. Click Create.

    The multicast interface is created and displayed in the table.

  7. In the upper part of the settings area, click Save to save the settings of the CPE template or CPE device.

Editing a multicast interface

You can edit multicast interface settings in a CPE template or on a CPE device. A multicast interface edited in the CPE template is automatically modified on all CPE devices that use this CPE template.

To edit a multicast interface:

  1. Edit a multicast interface in one of the following ways:
    • If you want to edit a multicast interface in a CPE template, go to the SD-WAN → CPE templates menu section, click the CPE template, and select the Multicast → Interfaces tab.
    • If you want to edit a multicast interface on a CPE device, go to the SD-WAN → CPE menu section, click the CPE device, select the Multicast → Interfaces tab, and select the Override check box.

    A table of multicast interfaces is displayed.

  2. Click Edit next to the multicast interface that you want to edit.
  3. This opens a window; in that window, if necessary, edit the multicast interface settings. For a description of the settings, see the instructions for creating a multicast interface.
  4. Click Save.

    The multicast interface is modified and updated in the table.

  5. In the upper part of the settings area, click Save to save the settings of the CPE template or CPE device.

Deleting a multicast interface

You can delete a multicast interface in a CPE template or on a CPE device. A multicast inerface deleted in the CPE template is automatically deleted on all CPE devices that use this CPE template.

Deleted multicast interfaces cannot be restored.

To delete a multicast interface:

  1. Delete a multicast interface in one of the following ways:
    • If you want to delete a multicast interface in a CPE template, go to the SD-WAN → CPE templates menu section, click the CPE template, and select the Multicast → Interfaces tab.
    • If you want to delete a multicast interface on a CPE device, go to the SD-WAN → CPE menu section, click the CPE device, select the Multicast → Interfaces tab, and select the Override check box.

    A table of multicast interfaces is displayed.

  2. Click Delete next to the multicast interface that you want to delete.
  3. In the confirmation window, click Delete.

    The multicast interface is deleted and is no longer displayed in the table.

  4. In the upper part of the settings area, click Save to save the settings of the CPE template or CPE device.
