Abstract: Embodiments are provided for partially replicating endpoint routing information, and comprise calculating a first shard interval of a key space based, at least in part, on capacities of a plurality of spine nodes in a network fabric. Embodiments also include mapping the first shard interval to a first spine node of the plurality of spine nodes, communicating shard mapping information associated with the mapping to a set of leaf nodes in the network fabric, and populating an endpoint repository in the first spine node with routing information for one or more endpoints corresponding to the first shard interval. More specific embodiments include calculating respective shard intervals for other spine nodes of the plurality of spine nodes based, at least in part, on the capacities of the plurality of spine nodes. In specific embodiments, the calculating the first shard interval is based, in part, on one or more dynamic parameters.

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: An example method for to inter-pod traffic redirection and handling in a multi-pod network environment is provided and includes receiving a packet with an overlay header outgoing from a first pod, identifying the packet as redirected based on a source address in the overlay header indicating a second pod and a destination address in the overlay header indicating a third pod, the first pod being distinct from the second pod and the third pod, setting a redirection bit in the overlay header tagging the packet as redirected, and transmitting the packet to the third pod.
