Abstract: Internet Group Management Protocol (IGMP) snooping includes flooding an IGMP query received at a border leaf switch from a multicast router connected to the multicast router to all host devices in a given bridge domain through leaf switches in the bridge domain, and receiving multiple join requests from the connected host devices at the leaf switches. The IGMP snooping also includes consolidating the multiple join requests received at the leaf switches into a multicast groups membership repository to indicate for each leaf switch the multicast group membership of interest in the given bridge domain, and sending the repository to the border leaf switch to enable the border leaf switch to send a consolidated IGMP proxy report on behalf of the leaf switches to the multicast router based on the repository and that indicates the multicast membership of interest in the given bridge domain.

Abstract: A packet is generated at a first network connected device for transmission to a destination network device through a network comprising a plurality of pods. At least two of the plurality of pods are within separate management domains, and generating the packet comprises generating the packet with a first identifier and a second identifier. The first identifier indicates a pod of the plurality of pods in which the destination network connected device is located, and the second identifier indicates an identity of the destination network connected device within the pod of the plurality of pods. The packet is transmitted from the first network connected device to the destination network connected device.
