Abstract
Techniques for multi-tenant overlays with per-tenant distributed routing are described herein. The techniques may include provisioning an overlay network such that tenants hosted by a forwarding plane of the overlay network are each configured to forward routing protocol packets to a routing control plane of the overlay network and the routing control plane of the overlay network is configured to determine routing paths between each tenant and respective destinations. A routing protocol packet may be sent to the routing control plane by a first tenant. The routing protocol packet may include an indication of a destination that is served by the first tenant. Based on receiving the routing protocol packet, the routing control plane may determine one or more routing paths between the tenants and the destination. Additionally, an indication of the routing path may be sent to the tenants.
