An improvement of backbone network security using DMVPN over an EZVPN structure

The purpose of this work is to promote an improvement of backbone networks in terms of availability and remote access. It especially focuses on network environments based on a hub and spoke topology. The significant findings indicate that data isolation, data encryption and encrypted dynamic routing information transmission are the main requirements for backbone network security. In addition, due to the importance of the backbone network, redundancy is also a necessary consideration for its availability, especially link and gateway redundancies. This report introduces a two-surface structure based on particular security protocols addressing backbone network security. The simulation of the proposed structure was carried out on GNS3, but a performance test on real devices is still needed for further research.
