Abstract
An inter-datacenter multicast system includes a first datacenter connected to a second datacenter. A first multicast router device is located in the first datacenter and includes at least one first multicast router interface that provides a link to the second datacenter, and a second multicast router device is located in the second datacenter and includes at least one second multicast router interface that provides a link to the first datacenter. The first multicast router device and the second multicast router device sync multicast routes with each other to enable each to act as respective designated routers, and also each remove multicast router interfaces that provides links to the other datacenter from outgoing interface Virtual Local Area Networks (VLANs) that are part of a multicast route, which prevents traffic tromboning and reduces multicast data communications between the first datacenter and the second datacenter.
