Analysis of IPSec Implementation on Dynamic Multipoint VPN Protocol Using Routing Border Gateway Protocol

Dynamic Multipoint Virtual Private Network (DMVPN) technology is one of Cisco's solutions to overcome the limitations VPN scalability. DMVPN has a combination components: Next hop resolution protocol (NHRP), Generic Routing Encapsulation (mGRE) and protocol. This research implements simple network consisting Hub, Spoke1, Spoke2, Lan1, Lan2 Lan3 using GNS3 simulator. study compares performance IPSec without IPsec on BGP parameters namely delay, throughput, jitter packet loss evaluate security impact network. The results this indicate that an effect sending UDP packets which have throughput value 5082.18 kbit/s while IPSec's 5034.40 kbit/s. 7.54% 4.79%. same value. delay 0.183s 0.410s. TCP delivery 1139.16 1105.20 0.185s 0.187s.
