vEOS Router ECMP HA Deployment Guide in GCP

vEOS Router ECMP HA Deployment Guide in GCP Introduction In this document we demonstrate deployment of Arista vEOS Router in Google Cloud Platform  (GCP). Currently, vEOS Router on GCP doesn’t support Cloud HA. We will use GCP routes and priorities to support HA and ECMP. A vEOS Router can be used to create a virtual machine instance that can be used to implement various GCP deployments such as edge routers and transit routers. This document provides a guide to deploy a hub-spoke topology in GCP. Overview Arista vEOS Router is a new platform release of EOS that is supported on Google...

Arista Hybrid Cloud – IPSec between vEOS Router and Linux

This document provides the steps and running configuration for setting up an IPsec connection between vEOS Router and a Linux Compute Node instance in AWS. On the Linux Compute Node Install Strongswan You might have to enable epel repository for yum on AWS. (https://aws.amazon.com/premiumsupport/knowledge-center/ec2-enable-epel/) yum install strongswan   Create a GRE tunnel on the machine ip tunnel add tun0 mode gre remote <ip addr on veos et> local <ip addr on client eth> ip link set tun0 up ip addr add <ip addr> dev  tun0 ip route add <prefix> dev tun0   In /etc/strongswan/ipsec.conf, add the configuration for the Ipsec...

Configurable IPv6 link-local address

An IPv6 link-local address for an interface is generated automatically using the modified EUI-64 scheme. All IPv6 enabled interfaces are required to have at least one link-local address, with a special prefix starting with “fe80::/10”. In this release, we provide the functionality to manually configure the link-local address of a given interface from the CLI using the ‘link-local’ keyword. Since, Link-local addresses are local to a segment it is possible for multiple interfaces on different subnets to have the same link-local address. This feature allows the network engineer to assign addresses according to a given scheme, and further helps in troubleshooting issues by isolating interfaces...
