Implementation of Dynamic Multipoint VPN over IPsec for Secure Enterprise Network

Abstract

The Purpose of this thesis is to promote an improvement of availability and remote access for secure enterprise network infrastructure by using dual hub dual DMVPN(Dynamic Multipoint VPN).using multipoint GRE (mGRE) over IPSec data transmission of enterprise network are reliably secure. DMVPN is a technology that implements different protocols concept such as IPSec encryption, next hop resolution protocol (NHRP), generic routing encapsulation (GRE) and provides dynamic and static IPSec tunnel between spoke to hub, spoke to spoke. In this book, we implement the technique of DMVPN to constructs secure enterprise network of enterprise organization and by using hot standby routing protocol (HSRP) to overcome the failure network. The simulation was done by GNS3 and packet capture by wire shark software. From the result of the test, DMVPN technology with HSRP protocols completely fulfills the real necessity that undertaking utilizes a system for enterprises. It offers a mode which is a fast, advantageous and practical venture and accessible up time network to an endeavor for building a safe and dependable network.
