So, network administrators who are fond of MikroTik Router can now configure, test and troubleshoot their MikroTik network with GNS3 so easily. MikroTik introduces Cloud Hosted Router (a RouterOS version) that is used to run as virtual machine and a virtual machine can easily be integrated with GNS3. GNS3 can talk a large number of network vendors including MikroTik. GNS3 is a network simulator software used by hundreds of thousands of network engineers worldwide to emulate, configure, test and troubleshoot virtual and real networks. Web.SeptemAbu Sayeed GNS3 Installation and Configuration Guides, MikroTik Router Tutorials & Guides This is fundamental in developing their understanding of the applications, which would lessen their workload (Novell, inc., 2011, p. For networking engineers anticipating to pass various certifications that come their way, it is quite vital to have an explicit understanding of GNS3, VPN, and IOS routers taking into account, their common usability. Setting VPN on GNS3 is quite easy but requires extensive research. Nonetheless, setting up a VPN project is complex and demanding. Work with VPN ProjectĪ virtual private network is very important in securing information passed between networked devices. Finally, the user should run the TFTP download again to start the recovery process (Cisco Systems, 2011, p. The user should then run the TFTP download command and thereafter type IOS information. Installing IOS to router requires one to ensure that TFTP is installed and configured. However, it is important to note that users are required to present their own IOS for use on the GNS3 platform. How to Install images (ISO) in the routersĪs had been stated earlier, GNS3 can be used to test features of Cisco IOS in routers. These can also be set up on GNS3, especially in experimental real lab checks to find their admissibility (Cisco Systems, 2011, p. The need to secure such transmissions allows the use of a VPN. It provides a way of extending uninterrupted voice, video, mobile, and data applications. IP telephony refers to the technologies, which employ the use of internet protocol’s packet-switched connections that exchange fax and voice, among others. This can be done using the SSL-VPN on the GNS3 platform (Dunbar, 2010, p. A lab for VPN can be set up using GNS3 for networking different devices. VPN can be enabled on GNS3 topology and is essential in enhancing its efficiency. This is usually done using secure cryptography. It enables the secure transfer of data between different networked devices without allowing other external access (GNS3dev, 2008, p. A virtual private network is a network that provides secure access to an organization’s network using an open telecommunication infrastructure, such as the internet. GnS3 is a strong complementary tool for use with VPN. In addition, it is utilized in verifying configurations that could be used afterward on real routers (GNS3dev, 2011, p. Furthermore, GNS3 can be used with Cisco IOS, and Juniper (JunOS). On the other hand, Qemu is an open-source device emulator, which is generic and virtualized. While Dynagen is a text-based front-end made for Dynamips, Dynamips is a program, which helps GNS3 in IOS emulation. GNS3 is powerfully linked to Dynamips, Qemu, and Dynagen. It is a powerful tool for real labs and is used by network engineers as well as other professionals to get certifications like CCNA, and CCNP, among others. GNS3 is a graphical network simulator, which provides a platform for the simulation of a complex network. This paper will try to define GNS3, explain how it works with VPN, IP Telephony, installation of images (ISO) in routers, as well as its complexity (Ciscoguides, 2011, p. GNS3 is a graphical network simulator platform, which is considered a powerful complementary tool for use by network engineers, as well as other computer professionals. To accomplish this, they need several complementary tools that provide a platform for the simulation of complex networks. Most administrators and network engineers desire to pass numerous computer certifications, for instance, CCIE, JNCIE, and CCNA among others.
