Arista Any Cloud Platform – Destination NAT (IP Anycast) in vEOS Router

Overview Purpose of this post is to test and validate Destination NAT (IP Anycast) support on vEOS Router.  We built the following topology in AWS to validate this setup:    Here is the link to the EOS Central article that can be referenced to help build this topology – https://eos.arista.com/arista-any-cloud-platform-hybrid-cloud-veos-router-in-aws-deployment-guide/ Objectives We hope to accomplish  the following in this article: Create a Loopback interface on vRouter-1a and vRouter-1b with an IP address of Advertise as an equal cost route to vRouter-Transit.  At any given moment vRouter-Transit could take the path to vRouter-1a or vRouter-1b.  In this setup we utilized BGP without...

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...
