Patent attributes
Aspects of the embodiments are directed to methods, systems, and computer program products for stitching route targets between disparate virtual private network domains. Embodiments are directed to a datacenter interconnect (DCI) network element that is configured to receive from a first network node of a first domain a routing prefix comprising a first route target value; determine that the first route target value is associated with a first route target set, the first route target set associated with the first domain; determine a corresponding second route target set associated with a second domain; create a second routing prefix that includes one or more route target values from the second route target set; and transmit the second routing prefix to a network node in the second domain.
