Claim:
1. A method, comprising: receiving a data packet in a data plane at a router located at an exit edge of an autonomous system (AS); determining a destination of the data packet and an associated AS-path information to the destination; selecting particular data packets for which the AS-path information is inserted from at least one of a particular type of data packet; a particular class of data packet; a particular priority of data packet; a particular protocol of data packet; or a particular size of data packet; inserting the AS-path information into the data packet in the data plane if the data packet is selected; and forwarding the data packet with the AS-path information toward the destination wherein a receiving device in a destination AS that receives the data packet validates whether the data packet in the data plane was routed through a path that was secure from a control plane perspective based on a collection of one or more insertions of AS-path information in one or more data packets received on the data plane.
