Select which command has to be executed when the container boots. This has to be the Linux init process which in turn launches the rest of EOS. As of version 4. Select the console type that GNS3 makes the node available on. Using the telnet console we can see the status of the init process, while we can use an auxiliary console if there is need to enter the CLI. Enter the environment variables. These are of vital importance for cEOS-lab to work. Drag the node to the canvas, then start it. To test if this all works we can add another node, then connect the two ends together and do a ping test.
Again, each node will need a unique system MAC address i. The serial number can be any arbitrary value i. Here are the commands:. Switch to the enable mode and shutdown the switch with the command:. Configure VMs settings according the picture below.
In order to tell Qemu to boot a file Aboot-veos-serial You can check the available interfaces with the CLI command show interfaces status. They are eight Ethernet interfaces shown on the Picture 3 at all. The command s how ip int brief shows only Layer 3 interfaces. I have created this interface for testing connectivity between two Arista appliances.
Arista Switches Configuration. The topology consists of two Arista switches and four computers, all these are emulated by Qemu. Switches are connected via Arista1 config vlan 10 Arista1 config-vlan vlan 20 Arista1 config-vlan exit. Arista1 config interface ethernet 1 Arista1 config-if-Et1 switchport mode access Arista1 config-if-Et1 switchport access vlan 10 Arista1 config-if-Et1 no shutdown.
Arista1 config-if-Et1 interface ethernet 2 Arista1 config-if-Et2 switchport mode access Arista1 config-if-Et2 switchport access vlan 10 Arista1 config-if-Et2 no shutdown.
Arista1 config-if-Et2 interface ethernet 3 Arista1 config-if-Et3 switchport mode trunk Arista1 config-if-Et3 switchport trunk allowed vlan 20 Arista1 config-if-Et3 no shutdown. Arista1 config interface vlan 10 Arista1 config-if-Vl10 ip address Arista1 config interface vlan 20 Arista1 config-if-Vl20 ip address Arista1 config-if-Vl20 ip routing Arista1 config-if-Vl20 router ospf 10 Arista1 config-router-ospf network Arista2 config vlan 20 Arista2 config-vlan vlan 30 Arista2 config-vlan interface ethernet 1 Arista2 config-if-Et1 switchport mode access Arista2 config-if-Et1 switchport access vlan 30 Arista2 config-if-Et1 no shutdown Arista2 config-if-Et1 interface ethernet 2 Arista2 config-if-Et2 switchport mode access Arista2 config-if-Et2 switchport access vlan 30 Arista2 config-if-Et2 no shutdown.

If the switch Arista 1 learned path to the network Thanks for the helpful guide, I was able to get up and running to test vEOS. I can connect Arista interfaces to each other in GNS3 and traffic flows just fine.
However, when connecting to any other devices, the link shows as up but no outside traffic seems to pass when viewing TCPdump. Any suggestions? I tried using e as well as some others, but no luck. I'm trying to add to my Cisco lab all of the cisco devices can see each other. I notices that I had to save my topology as the GNS3 project and then restart all devices. After that, I can ping between all devices. Maybe Qemu issue? So try to restart your devices and let me known.
Thanks for the super fast response! Yes, that worked and I can now ping between devices in GNS3. I still don't have reachability to physical devices via my breakout switch like I do with other devices, but I'll assume it's a GNS3 beta bug. I actually don't need to access outside devices from vEOS, I was just checking if it works.
If I get it figured out I'll update here. Either way your suggestion helped me out a ton. I wouldn't have thought of saving a non working topology, then reloading it to find it working. Thanks a lot! You've made a loyal customer out of me : and I'll be back here for sure.
Hi, great post. I've fired up a pair of Arista VMs virtualbox but can't ping between routers. CDP doesn't work either. GNS3 version is 0. Thanks Eamon. Eamon, I use GNS3 1. Beta3 is free now so you use it. Is it connection between R1 dot1q QinQ Arista working? What this means is that when building qemu from source, you can allow it to have more than 8 interfaces by changing that line.
I've been testing the Arista VM with 24 interfaces, and haven't noticed any issues so far other than I have to start the VM from the command line since GNS3 still won't recognize the change and caps the interface limit at 8. I take that back now that I think about it, max interfaces on this VM is I originally tried 24 and the VM crashed.
I dropped it down to 23 and it crashed, but 22 works. In the past, i've installed some cisco images in GNS3. My question is regarding about running ASAv in virtualbox. I can see an screenshot from your tutorial second part, virtualbox where you are listing all the vms you have emulated using Virtualbox in GNS3. In that list there is an ASAv listed. I'm trying to run ASAv in virtualbox asav Could you confirm me if is possible to emulate the Cisco's ASAv using virtualbox? If so, what is the tricky part?
Great article - thank you for putting this together. One correction I wanted to point out is that you have sudo and bash reversed on the shutdown command, it should be: bash sudo shutdown -h now. Mac OSX George, please, read this kvm how-to. Alternatively, you can omit -enable-kvm options but emulation is slow without kvm support. OK, will do.
