![]() ![]() Computers are running Linux Core and they are connected to Arista switchports with configured either VLAN10 or VLAN30 on switchports. IP routing must be enabled on both switches in order to forward traffic between VLANs. Switches are connected via 802.1q trunk with only traffic from VLAN20 allowed on trunk port. We are going to build a network topology that helps us to test configuration of VLANs, trunks and inter VLAN routing on Arista switches.The topology consists of two Arista switches and four computers, all these are emulated by Qemu. I have created this interface for testing connectivity between two Arista appliances. In addition to a default Management 1 interface, there is also an interfaces VLAN 1 presented on the Picture 4. The command s how ip int brief shows only Layer 3 interfaces. For instance, a vEOS Ethernet 1 is the interface Ethernet 1 of the vEOS GNS3 symbol. All other vEOS Ethernet interfaces shown in CLI match their particular GNS3 Ethernet interfaces. The interface Ma1 is a management interface and it corresponds to the interface Ethernet 0 of the vEOS symbol in a GNS3 topology. They are eight Ethernet interfaces shown on the Picture 3 at all. You can check the available interfaces with the CLI command show interfaces status. Interface Assignment Between GNS3 and Virtual EOS Picture 2 - Setting Boot Priority to CD/DVD-ROM for vEOS Qemu VMĤ. Navigate to Edit -> General Settings tab and set a parameter Boot Priority to CD/DVD-ROM according to the Picture 2. In order to tell Qemu to boot a file Aboot-veos-serial-8.0.0.iso from cdrom, you must configure vEOS VM Qemu templates as following: Configure VMs settings according the picture below. Navigate to Edit-> Preferences-> Qemu VMs. Switch to the enable mode and shutdown the switch with the command: When the switch boots up, login with the username admin (a password is not set). Please be patient as the process is really slow and it may take several minutes to complete.

The article describes how to set up vEOS virtual machine and connects it to GNS3 in order to test EOS functionality. Virtual EOS (vEOS) is single image and can be run as a virtual machine. EOS (Extensible Operating System) is Linux-based network operating system developed by Arista Networks that runs on all Arista switches. ![]()
