Techniques for a head-end node in one or more network autonomous systems to utilize a protocol to instantiate services on tail-end nodes. The head-end node can use a service request mechanism that is enabled by the protocol to request service instantiation on the tail-end node without a network operator having to manually configure the tail-end node, or even having access to the tail-end node. Additionally, the protocol may provide mechanisms to define handling attributes for traffic of the service (e.g., quality of service (QoS) attributes, Maximum Transmission Unit (MTU) settings, etc.), service acknowledgement mechanisms for the head-end node to determine that the service was instantiated on the tail-end node, and so forth. In this way, a head-end node can be used to instantiate a service on a tail-end node without a network operator having to have direct access to the tail-end node to manually configure the tail-end node.

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.
