Chirpstack Multicast Configuration = 634 + 635 + 636 +== 9.1 Introduction == 637 + 638 +ChirpStack has support for creating multicast-groups to which devices can be assigned. When enqueueing a downlink payload for a multicast-group, ChirpStack will analyze which gateways must be used for broadcasting to cover the complete multicast-group. This means that potentially, a single multicast downlink payload will be emitted multiple times. 639 + 640 +Multicast can be used for the following device-classes: 641 + 642 +* Class-B 643 +* Class-C 644 + 645 + 646 +== 9.2 Example to configure chirpstack Multicast == 647 + 648 + 649 +This section illustrates how to configure chirpstack Multicast.
