At present, people’s demand for the Internet is increasing day by day, and the scale of the Internet is exploding at an incredible speed. This also leads to the increasingly serious problem of routing scalability and mobility. The birth of the LISP network architecture provides an effective method to solve problems stated above. Consistency testing technology is the key technology to ensure the interconnection of network devices under the new network architecture. In this paper, aiming at the typical LISP mapping distribution protocol - LISP-ALT (RFC6836), a conformance testing system is designed and many testcases are implemented by standard TTCN-3 test language and open-source TITAN platform. Finally, a typical testcase is verified and analyzed for demonstration.
