Sharing transport interfaces between tenants on multi-tenant edge devices

A method comprising:

• receiving, from a tenant device in a first site of a multisite wide area network (WAN), a request for a virtual transport interface configuring the tenant device to utilize a transport service of the multisite WAN, the request indicating a physical transport interface associated with the tenant device and a type of the tenant device;
• determining, by a Software-Defined Networking (SDN) controller associated with the multisite WAN and based at least in part on the physical transport interface and the type of the tenant device, the virtual transport interface associated with the tenant device, wherein the virtual transport interface indicates one or more routing attributes associated with the tenant device;
• sending, to a first multi-tenant edge (MTE) device associated with the tenant device, the physical transport interface of the tenant device and the virtual transport interface associated with the tenant device;
• establishing one or more sessions between the first MTE device and one or more second MTE devices associated with the multisite WAN based at least in part on the physical transport interface, the sessions configured to enforce the one or more routing attributes on network traffic associated with the tenant device;
• and
• forwarding the network traffic associated with the tenant device based at least in part on the virtual transport interface via the one or more sessions.

One or more non-transitory computer-readable media storing computer-executable instructions that, when executed by one or more processors, cause the one or more processors to perform operations comprising:

• receiving, from a tenant device in a first site of a multisite wide area network (WAN), a request for a virtual transport interface configuring the tenant device to utilize a transport service of the multisite WAN, the request indicating a physical transport interface associated with the tenant device and a type of the tenant device;
• determining, by a Software-Defined Networking (SDN) controller associated with the multisite WAN and based at least in part on the physical transport interface and the type of the tenant device, the virtual transport interface associated with the tenant device, wherein the virtual transport interface indicates one or more routing attributes associated with the tenant device;
• sending, to a first multi-tenant edge (MTE) device associated with the tenant device, the physical transport interface of the tenant device and the virtual transport interface associated with the tenant device;
• establishing one or more sessions between the first MTE device and one or more second MTE devices associated with the multisite WAN based at least in part on the physical transport interface, the sessions configured to enforce the one or more routing attributes on network traffic associated with the tenant device;
• and
• forwarding the network traffic associated with the tenant device based at least in part on the virtual transport interface via the one or more sessions.
