【Abstract】 DMVPN can solve the problem of LAN secure communication between headquarters and branches of large companies. To alleviate the heavy load at the egress of the headquarters, this paper innovatively proposes the integration of DMVPN layered tunnel cloud and group encryption transmission technology. Double core and double key server are designed to avoid single point of failure. We use static route to ensure the real-time communication between sites, at the same time, simplify the configuration of each company’s exit site, which is conducive to maintenance and management.更多还原
