Abstract: Techniques for a hub node, provisioned in a site of a hub and spoke overlay network, to receive, store, and/or forward network routing information associated with a spoke, and send packets directly to spoke(s) that are remote from the hub node. A first hub node may receive a network advertisement including a border gateway protocol (BGP) large community string from a first spoke local to the first hub node. The first hub node may send the BGP large community string to a second hub node remote from the first hub node. The second hub node may decode network routing information from the BGP large community string and store the network routing information locally. The second hub node may send a packet from a second spoke local to the second hub node directly to the first spoke without the data packet being routed via the first hub node.

Abstract: Proposed herein at techniques for scalable network traffic steering in a multi-tenant network. In one aspect, a method includes receiving, at an ingress of a multi-tenant network, a data packet, the data packet including a Virtual Network Identifier (VNI) identifying a corresponding tenant for the data packet in the multi-tenant network, and determining, at the ingress, a corresponding cluster of routers for processing the data packet based on the VNI, wherein the corresponding cluster of routers is one of a plurality of clusters of routers in the multi-tenant network. The method further includes forwarding the data packet to a router in the corresponding cluster of routers for processing.
