Secure LAN Interconnection Through Efficient VPN
In Figure 1, a network management system (NMS) is used to manage switches when a large number of branch devices connect to the headquarters. The customer requires that communication data between the NMS and branch devices be protected.
Efficient VPN provides a method to simplify the configurations while ensuring network security. It allows you to perform complex configurations on the headquarters gateway and simple configurations on each branch gateway, freeing you from complex IPSec VPN configuration and maintenance and improving maintainability.
