Creating an IP multicast service

Before creating an IP multicast service, you must complete the following steps:

• Activate CPE devices.
• Create service interfaces for the traffic source and subscriber.
• Create a QoS rule.

To create an IP multicast transport service:

1. In the menu, go to the Infrastructure section.

   This opens the resource management page. By default, the Network resources tab is selected, which displays the table of SD-WAN and SDN Controllers.

2. Click Management → Configuration menu next to the SD-WAN Controller.

   This opens the Controller configuration menu. By default, you are taken to the Controller nodes section, which displays a table of Controller nodes.

3. Go to the IP multicast services section.

   A table of IP multicast services is displayed.

4. In the upper part of the page, click + IP multicast service.
5. This opens a window; in that window, in the Name field, enter the name of the transport service.
6. In the Source switch and Source port drop-down lists, select the CPE device and the service interface created on it that you want to use as the source interface.
7. To display service interfaces that were previously added to transport services in the Source port drop-down list, select the Show used interfaces check box. This check box is cleared by default.
8. In the Querier IP field, enter the IP address of the source interface.
9. If necessary, add a backup source interface through which traffic must be transmitted if the primary interface goes out of service:
   1. Select the Use backup interface check box. This check box is cleared by default.
   2. In the Backup switch and Backup port drop-down lists, select the CPE device and the service interface created on it that you want to use as the backup service interface.
   3. To display service interfaces that were previously added to transport services in the Backup port drop-down list, select the Show used interfaces check box. This check box is cleared by default.
   4. To stop using the backup service interface if the primary service interface is restored, select the Recovery auto-return check box. This check box is cleared by default.
   5. To build the multicast traffic distribution tree not only on the primary service interface, but also on the backup service interface, select the Backup multicast tree check box. As long as the primary service interface remains active, traffic packets on the backup service interface are dropped. This check box is selected by default.
10. Select the IGMP proxy check box to use an IGMP proxy server. This function keeps sending traffic to active multicast groups that have at least one service subscriber interface connected. This check box is cleared by default.
11. In the QoS drop-down list, select the previously created QoS rule for the source interface.
12. Click Next to proceed to the next group of settings.
13. In the Consumer switch and Consumer port drop-down lists on the right, select the CPE device and the service interface created on it that you want to use as the subscriber interface.
14. To display service interfaces that have been previously added to transport services in the Consumer port drop-down list, select the Show used interfaces check box. This check box is cleared by default.
15. Click + Add to add the service interface to the transport service.

    The service interface is displayed in the lower part of the window. You can delete a service interface by clicking Delete next to it. To continue configuring the IP multicast service, you must add at least one service interface.

16. Click Next to proceed to the next group of settings.
17. In the IP address field, enter the IP address of the multicast group. Range of values: 224.0.0.0 to 239.255.255.255.
18. In the Mask drop-down list, select an IP address mask. Range of values: 24 to 32.
19. In the GBR drop-down list, select the guaranteed bit rate (GBR) for the multicast group.
20. Click + Add to add the multicast group to the transport service.

    The multicast group is displayed in the lower part of the window. You can delete a multicast group by clicking Delete next to it. To continue configuring the IP multicast service, you must add at least one Multicast group.

21. Click Create.

The IP multicast service is created and displayed in the table.
