Abstract: Given the transition problem to IPv6 network, this paper introduces the principle of dual stack, and designs a dual stack transition experiment scheme based on eNSP. The key configuration method of the experiment is given, and the experimental results are analyzed and verified by Disp, Ping and other commands. Experiments show that dual stack technology can realize smooth transition to IPv6 network. The experiment helps learn the knowledge of IPv6 network, understand the principle of IPv6 network deployment, and master the configuration method of dual stack transition technology.
