If you want them to go away, click it again. If you want them to be visible, click on this icon: You will not that the interfaces that are in use do appear in the topology diagram. I have configured a trunk link between my two switches. The corresponding configuration exists for Client2 on SW2. You can see in the output above that VLAN 10 is active on port Fa1/0. I have also configured each client to be assigned to its respective VLAN. Here is the output of that command on SW1:Īs you can see, I have created both VLAN 10 and 20 on this switch. The command to view the VLANs you have created is show vlan-switch. Here is the question mark help information from that mode: Once you are finished creating VLANs, apply your settings and then exit the vlan database mode. Then create the desired VLANs with the command vlan xx (where xx is the desired VLAN ID).

Here is how to create VLANs on an etherswitch module in GNS3:įrom privileged exec mode, type vlan database.

The method of adding VLANs on an etherswitch module is a little different from how it is done on a 2900 series switch, but the end result is the same. I added VLANs on each of the two switches – one for each client. The client configuration is straightforward – I put an ip address on each of the f0/0 interfaces, set speed and duplex, and no shut them. R2 is also a 3725-series router which I have left performing the role of a router, in this case, it has been configured as a Router-on-a-stick. I did so just to show it can be done, but that WIC-2T in the picture is not used in my topology.

Down below you see that, if the device supports it, you can add serial interfaces to your device. The NM-16ESW is the etherswitch module which I have selected to occupy slot 1 in my device. Once that is selected, it looks like this: Right click on the router (while it is shut down), and one of the options is Configure: Here is how to configure the etherswitch module. This configuration allows virtually all of the commands you need in order to practice for your CCNA Routing and Switching exam. They are both 3725 routers which have been configured with an etherswitch module. They are both routers which are assuming the role of Layer 2 switches in my scenario. The same goes for the switches – SW1 and SW2. If you choose this option, you can choose from a large number of devices – one of which is the computer I have shown in my topology. Take a look:īy right-clicking directly on the device, I see the drop-down menu shown. The next order of business is to explain why there is a picture of a computer if the device is actually a router. When IP routing is disabled, the ability to get to remote networks results from the above ip default-gateway command.

Normally routers have a gateway of last resort which results from a default route. This command is: (config)# ip default-gateway x.x.x.x When IP routing is disabled, another command which is normally ignored by routers now takes on a significant role. To accomplish this, I have disabled IP routing on each of them using this command: (config)# no ip routing The client machines are really routers assuming the roles of IP endpoints. Anyway, here is a screenshot of my topology for this blog: There is also the option of clicking File and then Take a screenshot, but the camera icon is so much more fun. A GNS3 user can generate a screenshot of the topology of a project at any time using the camera icon: I have changed some aspects of the topology so that the configuration is not identical (what fun would that be?) but the goal is to allow traffic generated from a host in one VLAN to reach, and return from, another VLAN. I am using what is, at the time of this writing, the latest version, which is 1.2.1. The concept is the same, the Cisco commands are the same, I just want you to see it inside the wrapper of the new and improved GNS3. One of the things that is included in the body of knowledge necessary to pass the current CCNA Routing and Switching certification exam is how to configure inter-VLAN routing using a router with a trunk link (hereinafter and evermore referred to as Router-on-a-stick!) If you read my previous blog on the topic Walk softly and carry a Router-on-a-stick! (ROS), much of the material in this blog will be familiar. My goal is to demonstrate how similar it is to configure the new GNS3 if you are already used to the previous version.
#Router on a stick configuration example install
In this blog I will presume that you have already taken the steps to install it. Have you had a chance to build some projects in the new rev of GNS3? If you have not done so yet, I would highly recommend heading over to GNS3 and downloading it.
