Techniques for allowing software defined (SD) network fabrics to accept network devices from other fabric technologies

A network device comprising:

• one or more memories collectively storing computer-executable instructions;
• and
• one or more processors coupled to the one or more memories, the one or more processors being collectively configured to execute the computer-executable instructions to cause the network device to perform an operation comprising:
• establishing a communication session between the network device and a first network node, wherein the network device is a controller of a first network fabric that supports a first control plane, the first network node is within a second network fabric different from the first network fabric and supports a second control plane different from the first control plane, and the communication session is established using the second control plane;
• importing, via the communication session, first routing information from the first network node into a first routing table of the first control plane, wherein the first routing information comprises a first endpoint identifier of the first network node, the first endpoint identifier being associated with a first overlay identifier for the first network node;
• and
• exporting, via the communication session, second routing information from at least one second network node within the first network fabric into a second routing table of the first network node.

A non-transitory computer-readable medium comprising computer program code that, when collectively executed by one or more processors, performs an operation comprising:

• establishing, by a controller of a first network fabric that support a first control plane, a communication session between (i) a first network node within a second network fabric different from the first network fabric and (ii) the controller, wherein the first network node supports a second control plane different from the first control plane, and the communication session is established using the second control plane;
• importing, by the controller via the communication session, first routing information from the first network node into a first routing table of the first control plane, wherein the first routing information comprises a first endpoint identifier of the first network node, the first endpoint identifier being associated with a first overlay identifier for the first network node;
• and
• exporting, by the controller via the communication session, second routing information from at least one second network node within the first network fabric into a second routing table of the first network node.
