![]() ![]() Right click your router->configure->memories and disks and just increase the size of the first PCMCIA disk0 (verify the size by issuing a dir flash: from the router CLI)Īfter that, configure cme the same as on a physical router. You can't do it straight from flash to flash, because it will give you a message saying 'Device in exclusive use', you can use tftp as well, its just that ftp is much faster.Īlso, the standard flash size is 16Mb, so you might want to increase that. I have installed an older version to go with 12.4.15T on a 3725. If CME would be a car, it would be a Tata Nano. Step 1 After running the GNS3 network simulator software, create a new project. I find better than running 2 or more softphones on a single laptop.ĬME and GNS3 For the record, I don't like CME, I actually avoid it like the plague. Follow the steps below to add Cisco’s Router or Switch to your GNS3 server. I use this so I can actually run multiple softphones on different physical machines. This, combined with adding static routes in your home network to point to the GNS3 subnets, should allow you to connect to GNS3 from any machine. HKEY_LOCAL_MACHINESYSTEMCurrentControlSetservicesTcpipParameters and set the IPEnableRouter value to '1', and then reboot. This is quite easy to set up and for this you will need to ebale IP routing in the registry (again using Win7 64bit). The way to do this is to have the laptop perform routing between your home network and GNS3. To add to this, I have connected my home network subnet to GNS3 through the same loopback interface as described above. For this lab, we can use a simple static routing.įor example, on R1, you can do the following.Please also remember that if you expand your GNS3 subnets beyond the direct connected subnet of the loopback interface, you will need to add static routes to your laptop or desktop (and change your proxy setting exlcusions to include these networks). In order PC1 to communicate with PC2, you need to configure routes.

After that, you can double click on individual nodes to start a telnet session to it. In GNS3, create a new project named “Lab-1” containing:ĭouble click on “Cisco 3600” router and in the “Slots” tab add “NM-4E” in the slot 1.ĭouble click on “Cisco 7200” router and in the “Slots” tab add “PA-8E” in the slot 1.Ĭonnect PC1 (Ethernet0) with R1 (Ethernet1/0)Ĭonnect PC2 (Ethernet0) with R2 (Ethernet1/0)Ĭonnect R1 (FastEthernet0/0) and R2 (FastEthernet0/0)Ĭlick “Run” button to start the emulation.

The left pane of the Preferences window should propose you, among other topics, the Qemu VMs, VirtualBox VMs and VMware VMs allowing you to create new GNS3 end device nodes by importing the selected virtual machine. For our purposes, we can simply run everything on the host machine (no need for GNS3-VM). To import a virtual machine, from GNS3 menu bar go in Edit > Preferences. ![]() While the software itself is free and it can emulate various types of hardware, the licensing of actual Cisco software is a complex issue.įor this and future labs we will need Cisco 3660 and Cisco 7200 platforms and you can download and 5.bin images from Canvas (or Internet). It is available for Windows, Mac, and Linux. Go to GNS3 Webpage and download GNS3 application for your platform. The goal of this project is to install and configure GNS3 software and emulate/configure a simple network. Install Cisco 3660 and Cisco 7200 templates Lab 1: Simple Network Emulation with GNS3 ![]()
