Normalized lookup and forwarding for diverse virtual private networks

A computer program product, comprising:

• a non-transitory computer-readable medium having computer-readable program instructions embodied thereon that, when executed by a transit network computer associated with a transit network, cause the transit network computer to:
• receive, from a first network computing device of a first network, a map request associated with a packet;
• extract a destination identifier from the map request;
• determine a network type associated with the destination identifier;
• generate a mapping associated with the network type, the mapping comprising a route from the first network computing device of the first network to a second network computing device of a second network associated with the destination identifier;
• and
• transmit, to the first network computing device of the first network, a map reply comprising the mapping.

A system, comprising:

• a transit network storage device;
• and
• a transit network processor communicatively coupled to the storage device, wherein the transit network processor executes application code instructions that are stored in the transit network storage device to cause the system to:
• receive, from a first network computing device of a first network, a map request associated with a packet;
• extract a destination identifier from the map request;
• determine a network type associated with the destination identifier;
• generate a mapping associated with the network type, the mapping comprising a route from the first network computing device of the first network to a second network computing device of a second network associated with the destination identifier;
• and
• transmit, to the first network computing device of the first network, a map reply comprising the mapping.
