Cumulus content roundup: November
We’re at it again with the Cumulus content roundup- November edition. As always, we’ve kept busy this month with lots of great resources and news for you to read. From EVPN Underlay Routing Protocol to the benefits of Layer 3, we’ve rounded it all up right here, so settle in and stay a while!
From Cumulus Networks:
Choosing an EVPN Underlay Routing Protocol: We take a look at the options in routing protocols that could use as an underlay with the objective of understanding what might make them a fit or not for deployment in an EVPN network.
The Benefits of Flexible Multi-Cloud and Multi-Region Networking: Here we explore some of the reasons multi-cloud is fantastic for enterprises when they consider security, flexibility, reliability, and cost-effectiveness.
Cumulus Linux Automation with Standard Linux Tooling: This blog focuses on the different options available for modern automation, & how the Cumulus Linux approach provides the greatest amount of flexibility.
Cumulus Networks Open-Ended NCLU Net Example Command: NCLU is the always helpful Network Command Line Utility and supports both inspection and modification of Cumulus Networks configuration data.
Layer 3 can do it better. I’m convinced. You should be too.: Are you bringing the best solution Continue reading
BiB 062: Globally Scalable Microsegmentation With Illumio
Illumio is a security company focused on preventing breaches from spreading through an organization using microsegmentation. In this briefing, Illumio discussed their Policy Compute Engine Supercluster. The PCE Supercluster is, as the name implies, a cluster of Policy Compute Engines that spans regions or even the globe. Illumio cited several scenarios driving this available architecture of their central controller.

Logs from the Edge
With Cloudflare Workers, our JavaScript environment at the edge, it is possible to send traffic logs to arbitrary locations. In this post we are going to discuss an example Worker implementation on how to achieve this. So if you are building or maintaining your own traffic logging/analytics environment, read on.
To build the underlying script we are going to leverage sub requests. Sub requests, which can be spawned from the initial HTTP/S request, can be used to aggregate and compose a response from several back end services, or, like in the example discussed here, to post data to a specific endpoint. Sub requests can be made asynchronously and after the initial request has been fully served to avoid adding unnecessary latency to the main request.
The Worker Code
In this example we assume an Elastic stack has been set up at elk.example.com and has been configured to receive via HTTP/S PUT requests a number of fields for each log line. The full script that we are going to look at can be found below:
addEventListener('fetch', event => {
event.respondWith(fetchAndLog(event));
})
async function fetchAndLog(event) {
const response = await fetch(event.request);
event.waitUntil(logToElk(event.request, response));
return response;

Interview: Active-Active Data Centers with VXLAN and EVPN
Christoph Jaggi asked me a few questions about using VXLAN with EVPN to build data center fabrics and data center interconnects (including active/active data centers). The German version was published on Inside-IT, here’s the English version.
He started with an obvious one:
What is an active-active data center and why would I want to use an active-active data center?
Numerous organizations have multiple data centers for load sharing or disaster recovery purposes. They could use one of their data centers and have the other(s) as warm or cold standby (active/backup setup) or use all data centers at the same time (active/active).
