In this article, we will communicate two different networks by enabling the OSPF routing protocol on Cisco Routers using the GNS3 network simulator program. In the previous article, we explained in detail the OSPF protocol. The biggest difference between the OSPF and EIGRPprotocols is that EIGRP is only a routing protocol specific to Cisco devices. So the OSPF protocol can easily determine the best way to the destination.

In addition, for example, Routers in the AS 1 field can communicate with the Router in the AS 2 field.Įvery router in the AS has full network topology information. Routers configured with the same AS number can communicate with each other. The OSPF routing protocol provides additional security on the network using Autonomous System (AS) numbers.

How to Configure OSPF on Cisco Router in GNS3? OSPF uses the Dijkstraalgorithm to recalculate routing routes on any network change. How to Configure OSPF on Cisco Router in GNS3? – OSPF (Open Shortest Path First)routing protocol is the Dynamic Routing protocol. Here you can input/enter all the IOS commands to configure the device. Right click on the device, then select “ CONSOLE” option a window will appear where you can configure the device with as per your wish.
Then select the router and drag it workspace area, now click on run button or navigate to ->Control menu and click start/resume all the devices option to run the device.

Step 3: Now import the image of the router you would like to install on gns3 VM by clicking on option browse then say YES to “decompress” the image.Note: There is another option “Run IOS Router on Local Machine” this option was used before the introduction of “GNS3 VM” however, we have GNS3 VM so we will go with the latest option to achieve good performance and emulation. Step 2: Now click on new and select option “Run IOS Router in GNS3 VM” and press NEXT.Step 1: Open the gns3 VM then navigate to -> Edit->preferences -> Dynamips -> IOS routers.To perform router installation, we need to have an IOS image. Gns3 has a feature called Dynamips which allows us to install( CISCO IOS) image and emulate the router environment. Today, we’ll install a device on GNS3 VM that is not available in GNS3 Marketplace (CISCO IOS). The blog is for the users who would like to simulate the router environment in GNS3VM irrespective of the vendors (Cisco, Juniper etc.) In my earlier blog, I explained how to install and configure the GNS3 VM and how to configure a device through a template (from GNS3 Marketplace). How to Add Cisco IOS to GNS3? In the next window, select the Add an IOS Router using a real IOS image (supported by Dynamips) option. Learn and watch on how to add IOS images in GNS3.
