Abstract: An example method for to multicast traffic distribution in a multi-pod network environment is provided and includes provisioning a block of multicast group addresses for broadcast, unknown unicast and multicast (BUM) traffic distribution between pods in the multi-pod network, calculating a hash corresponding to a bridge domain (BD) extending across a plurality of pods in the multi-pod network, the hash being identically calculated at each one of the plurality of pod, indexing with the hash into the block of multicast group addresses designated for inter-pod BUM traffic to derive a global multicast group identical for the broadcast domain across the plurality of pods, and associating a local multicast group at the translator with the derived global multicast group.

Abstract translation: 提供了一种用于在多荚网络环境中组播业务分布的示例性方法，并且包括为多荚网络中的荚之间的广播，未知单播和多播（BUM）流量分配提供多播组地址块，计算散列 对应于跨多个pod网络中的多个pod延伸的网桥域（BD），该散列在多个pod中的每一个pod处被相同地计算，用散列变换成指定用于inter- pod BUM业务以导出跨多个pod的广播域相同的全局多播组，并且将转换器处的本地多播组与导出的全局多播组相关联。
