Abstract: Techniques for using global virtual network instance (VNI) labels in a multi-domain network to route network data with a multi-tenant network overlay are described herein. A routing device provisioned in a network domain of the multi-domain network may register with a service discovery system of the network domain for use of network configuration data to establish routes through the multi-domain network with network nodes. Each network domain of the multi-domain network may include an application programming interface (API) server for processing API requests to make changes to configurations of a network domain. A border gateway protocol (BGP) large community may be utilized to encode global VNI labels, network addresses, local next hop nodes, and/or additional network information and sent to routing devices provisioned in separate network domains. A service chain may be signaled by global VNI labels to route network traffic through various services prior to reaching a destination endpoint.

Abstract: Techniques for a hub node to, provisioned in a network site of a hub and spoke overlay network, to receive a network advertisement from the spoke, decode network routing requirements from a border gateway protocol (BGP) large community associated with the network advertisement, and store the network routing requirements in association with a route associated with the spoke. The routing requirements may indicate one or more service(s) to be applied to the packet, a trust level associated with the spoke, and/or a trust zone associated with the spoke. The hub node may receive a packet from the spoke to be transmitted to destination spoke. The hub node may then route the packet to the destination spoke, drop the packet, or send the packet to a service node configured to apply the one or more services to the packet based on the routing requirements.
