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

Analisa Perbandingan Performansi Hot Standby Router Protocol (HSRP) dengan Gateway Load Balancing Protocol (GLBP) Pada Router Spoke DMVPN

The use of internet connections to develop Virtual Private Network (VPN) lines in companies has been massively applied. An example is the use of Dynamic Multipoint VPN (DMVPN) technology from Cisco, which can connect Spoke or branch offices through HUB or data centers. Besides requiring a secure network, companies also need high network availability. One of them is by using the redundancy method in order to minimize downtime when device damage occurs. In this research, the spoke router will apply two redundancy methods by Cisco, which are Hot Standby Router Protocol (HSRP) and Gateway Load Balancing (GLBP). This research aims to compare the QoS performances and downtime between the two protocols in order to discover the suitable method for DMVPN networks at branch offices. The test scenario is conducted on the GNS-3 simulator using the File Trasnfer Protocol (FTP) service. The obtained test result shows that the HSRP throughput value is smaller from the GLBP with a difference of 0.20%, the increase in the average delay of the HSRP is smaller from the GLBP with a difference of 1.07%. The HSRP data transfer time is faster than GLBP with a difference of 1.49%, and HSRP downtime is 4.13% faster than GLBP. The conclusion is that a suitable redundancy solution for spoke router using the HSRP method

Building Dynamic Mesh VPN Network using MikroTik Router

Dynamic Multipoint Virtual Private Network (DMVPN) is a VPN technology to form an automatic, fast, and dynamic logical mesh network. DMVPN is a proprietary technology from Cisco, so this technology is not available on MikroTik routers.

This paper discusses the usage of OpenVPN and Open Shortest Path First (OSPF) to form a Dynamic Mesh VPN network using MikroTik routers inside the GNS3 simulation environment. The final part of this study proves that this solution can help the routers that do not equipped with the DMVPN technology to form a Dynamic Mesh VPN network

EVALUASI KINERJA JARINGAN DMVPN MENGGUNAKAN ROUTING PROTOCOL RIPv2, OSPF, EIGRP DENGAN BGP

Data communication has become a major requirement for companies and governmental institutions. Communication is not only limited to one particular local area but covers other areas so as to form a wide network (WAN). By using 3-phase DMVPN (Dynamic Multipoint Virtual Private Network) technology, government companies and institutions can communicate securely through the Internet network at lower cost and easier in configuration than similar solutions such as X.25, Frame Relay and ATM. In maximizing the performance of DMVPN required good network management, one of them by using a combination of internal and external routing protocol. In this study the routing protocol used RIPv2, OSPF, EIGRP and BGP with different algorithms, to compare them used QoS criteria (throughput, jitter, packet loss, network covergence).
