Once you have placed a router in the environment, save a copy of the configuration to disk. This is because the non-XM models have insufficient memory to accommodate the SDM installation. If you already have a platform you want to be able to interact with then ignore this step, otherwise, you should launch GNS3 and create a new environment containing the model router with the appropriate amount of memory and the appropriate IOS image available to support the use of SDM.įor my purposes, I am using a Cisco 2651XM router because I have just purchased one, however if you are doing this purely virtually then you can use any 2600 Series model from the XM branch. Step 3: Create a Virtual Network Platform You need to reboot at this stage to allow Dynamips to be able to detect the new adapter.

Once you have selected it, hit the Next button to install the hardware. Select Microsoft from the manufacturer column on the left and scroll down to select Microsoft Loopback Adapter from the list on the right. On the next page, you will be presented with a list of available network adapters which you can add. Click Next to do so.įrom the list of hardware types, select the Network adapters category, and then select Next. Once the scan for new hardware is complete, you will be given the option to press Next to manually search for the hardware.

Unless you have some pending hardware adds or changes you will not see any new hardware detection during this stage. From the context menu, select the option Add Legacy Hardware.Īt this point, allow the wizard to search for and install hardware automatically. At the Run dialog, enter the command compmgmt.msc to open Computer Management.įrom Computer Management, right click on the parent level item which is displayed as the hostname of your computer (RGREEN00 in my case). To do this, hit Start + R on your keyboard to open the Run dialog. Step 1: Installing a Loopback Network Interface If you are using GNS3 and Dynamips then follow these steps to get SDM working. Parts of the ICND1 exam require knowledge of the Cisco SDM GUI application, however as it stands you cannot access the routers and switches within your GNS3 environment.Ī link on the GNS3 forum takes you to a video which someone has produced providing instructions on how to access and use SDM for your virtual routers, however instructions are for Windows XP and cannot be followed for Windows 7. I am currently experimenting with the GNS3 and Dynamips network emulation platform to help me get to grips with some of the Cisco IOS commands for my CCNA, and I ran into a problem yesterday.
