NCClient Example with EOS

Introduction Ncclient is a python library that provides a set of tools to interact with and manipulate devices supporting NETCONF server functionality. The goal of this article is to assist users to leverage ncclient effectively with EOS. This article will outline the use of  ncclient to configure Arista devices using EOS CLI commands, as well as YANG modelled data (and a combination of the two).  This article is not intended to be a full tutorial on YANG or EOS supported YANG models. Arista EOS strives to support open YANG models via support of OpenConfig models wherever possible. At times vendor...

Configurations and Optimizations for Internet Edge Routing

Introduction For many years, network deployments for enterprise Internet edge environments have consisted of dedicated routing platforms and a switching or aggregation layer to distribute this to various network zones.  With the advances in merchant silicon forwarding engines and the software expertise put into Arista’s Extensible Operating System (EOS), we can now fully replace this legacy architecture with a collapsed routing and switching layer using Arista R Series platforms.  Arista R Series platforms allow for holding a full copy of the Internet routing table for both IPv4 and IPv6 in hardware (the Forwarding Information Base, or FIB) with plenty of...

DCS-7280SR2K with FLEXROUTE – A real world use case

When Arista introduced R-series back in 2015 (publicly announced, available in 2016), it was a game changer. For the first time in networking history, a switch with merchant-silicon chips was capable to absorb full IPv4 and IPv6 internet tables. This valuable capability opened a full set of new addressable use cases to all vendors which leveraged off-the-shelf ASICs to implement the device forwarding plane. Since then, two more generations have been released, namely the R2 and R3 platforms and these platforms further enhanced both performances and, more relevant to our discussion, scaling. Arista Networks has several routers to address Internet...
