Deploy a Transit VPC with vEOS using IGW (Public IP)

Deploy a Transit VPC with vEOS using IGW (Public IP) fanyang@arista.com   This document focuses on the steps to build a Transit VPC solution using Internet Gateway (IGW) vs. VPC peering. There are certain advantages to use IGW as transport. This eliminate the limits on how many VPC peering can be created and gives customer a larger scale deployment. It also enables spoke VPCs to communicate with each other directly with one hop, which can potentially save data cost. Besides, even it’s public ip to public ip communication, if both IPs belong to AWS, AWS will route the traffic through...

Arista Any Cloud Platform – vEOS Router in Azure Deployment Guide

Introduction In this document, we will demonstrate the deployment of Arista’s vEOS Router in Microsoft Azure. A vEOS Router can be leveraged to implement various Azure architectures such as the transit-edge or hub-spoke architecture. This particular document provides a step-by-step guide to deploy vEOS Router in a transit-edge architecture in the Azure public cloud. Overview Arista’s private and public cloud infrastructure both offer significant efficiencies that make it a compelling option for workload placement.   We have proven this in the private cloud with a simple yet scalable Spine/Leaf topology utilizing industry standard protocols across all of Arista switches. With...

Arista Any Cloud Platform – VM Migration

Introduction In many scenarios, resources are provisioned in the public cloud as a service, without a need to connect to a private on-prem environment. Situations will arise where connectivity is required between a public and private environment that conflict in IP space. This article will showcase how to leverage vEOS Router in AWS to establish connectivity between a VPC and a private on-prem datacenter that conflict in IP space. In this particular example, there are a hand-full of VMs that need to be migrated from AWS to a private environment. Objective Establish connectivity between the AWS VPC and the private environment. Once connectivity is established,...

vEOS on ESXi – Jumbo MTU Problem

Hi, I run couples of latest vEOS switches on ESXi, trying to build a VXLAN lab to test. Between vEOS switches, I used standard virtual switch as a virtual cable for each individual connection.  In vSwitch settings, I’ve set the MTU to 9000. MTU1500 works OK. But ping test over 1500 bytes all failed. PING 172.16.11.0 (172.16.11.0) 1473(1501) bytes of data. ping: sendmsg: Network is unreachable ping: sendmsg: Network is unreachable ping: sendmsg: Network is unreachable Searching over Internet came up no result…. Any thought?  

vEOS-Lab on Hyper-V

Introduction There are multiple ways to setup a vEOS-Lab environment if you have a linux system or on hypervisors such as VMware ESXi, vCenter, VM Workstation, VM Fusion, Virtualbox, etc using the vmdk provided in the Software downloads page. But if you have a Windows machine or a Windows server, the vmdk will not be useful. So here are the steps on how you can convert the vmdk to a  vhdx and create a vEOS VM on Hyper-V. Pre-requisites 1. Hyper-V Manager and Hyper-V 2. vEOS-Lab vmdk 3. Aboot ISO  Instructions Steps 1. Download the vEOS vmdk for the EOS version...

Arista Any Cloud Platform – Security Use Case

Introduction In this document we will demonstrate how to effectively leverage Arista’s vEOS Router in a Transit – Edge VPC model to satisfy a common security use case. As most companies look to move into the public cloud space, security vulnerabilities have gained more focus than ever before. Objective Provide a centralized security model within an AWS region, which will allow for ease of visibility and control. Deploying separate AWS Internet Gateways in every VPC, increases complexity and vulnerabilities in the public cloud space.  Prerequisites This document assumes that you have the following architecture deployed: A Transit – Edge VPC topology deployed...

Using vEOS for ZTP tests, cannot find any serial number

Hi! Using the vEOS to setup a docker container handling ZTP.No about ztpserver but I need to manage multiple vendors so I’m placing something in front handling all of them. Noticed that the serial number is empty in the image. Wondering about the possibilty of tweeking on in?Will try to get the image into single user mode and look myself but I guess this will be a timeconsuming task.   Any ideas??   Thanks! Fredrik

Agent unable to connect to Sysdb

I’m relatively new to EOS, so I feel like I’m probably missing a basic step. I’ve setup a vEOS testlab, running under KVM.  Most things have been going well, the virtual switches can see each other, i’ve been able to test some ZTP scripts. I’m getting stuck however when it comes to running an agent using the python sdk.  I’m attempting to start the HelloWorld.py from this example (https://github.com/aristanetworks/EosSdk/wiki/Quickstart:-Hello-World) However, all I get when looking at the agent logs is “waiting for connection to Sysdb …..” and it never connects. veos-vdf-core1#configure veos-vdf-core1(config)#daemon HelloWorldAgent veos-vdf-core1(config-daemon-HelloWorldAgent)#show active daemon HelloWorldAgent exec /mnt/flash/HelloWorld.py no...

Arista eapi multiple commands not working

Hi, When I’m trying to use Arista veos eapi to configure vlan on an interface using multiple commands, it is failing (single command is working fine like “show vlan”, “show version”). It is not showing any response and in the background also configuration is not happening on the virtual switch. Please help me if I’m missing anything. I’m using VEOS (virtual switch) for my testing. Following are commands I’ve used and attached the screenshot of eapi. Thanks in advance   enableconfigureinterface Ethernet1switchport access vlan 745show vlan 745

vEOS on GENI Experimental Portal

Hi, I am trying to use vEOS on GENI experimental portal as it seems ideal for my requirements. To do this I need to create a GENI image as given by http://www.exogeni.net/2014/07/creating-a-custom-exogeni-image-using-virtual-box/ So I tried to use vEOS 4.16.9M with Aboot 2.1.  But according to the GENI guide mentioned above, I need to create and save the OS image locally (in the guest VM). I am unable to mount an extra disk drive to my virtualbox (or use the pendrive). If you could help me with this, I would appreciate it greatly. Also, I tried to use the .swi file...

Running vEOS in Openstack

I’m trying to setup a vEOS lab environment in our internal Openstack infrastructure.  This is what I’ve done so far:- Uploaded the ABOOT image (Aboot-veos-8.0.0.iso) & the VMDK (EOS-4.18.0.vmdk) to Glance. Create a volume based on the VMDK Launch an instance from the ABOOT image with the Volume mapped to the instance:- nova boot –flavor m1.small \                 –image <aboot image ID> \                 –nic net-id=<Neutron Net ID> \                –block-device id=<Volume ID>,source=volume,device=hdb,dest=volume,shutdown=preserve \                veos-test-01 However, the instance hangs after loading the initrd & doesn’t run aboot. Has anyone tried this / had this working?

Management interface down

Configuration Session on vEOS

Hello everyone, I got the vEOS running on Virtualbox integrated with GNS3, so far everything running fine. Im trying to find out if the configuration session feature is not available on the vEOS or maybe im missing somthing. I’ve tried to issue the command : configure session from enable mode but it looks like there is no such command. Did anyone else encountered the issue?   Best Regards, Chen.
