In the third installment of this 9-video series, Russ White clarifies exactly what a fabric is, complete with drawings, animations, and live illustrations. From there, you’ll be able to determine what is and is not a fabric. In this lesson, Russ also walks through traffic patterns, tiers, and bandwidth between tiers in data center fabrics. […]

Typically when people hear the word edge, everyone gets a little apprehensive of what that means. So Josh, Andy, Martin and Chad got together to collaborate on what that means from their collective experiences across multiple industries. In this blog we will cover what the difference is between the near edge and far edge, as well as give some examples of what we have seen in these environments across multiple industries.
Near edge typically refers to distributed deployments of “scaled-down” IT-like services to support business operations outside the core data centers and public cloud providers. This includes anything from retail stores, branch field offices, manufacturing facilities, warehouses and distribution centers that generally have stable connectivity.
Traditionally, these have been referred to as remote offices or branch offices, with the common acronym ROBO, but there are far more examples of this deployment pattern. Consider the following:
These are all examples that fit under our definition of Continue reading
While researching the BGP RFCs for the Three Dimensions of BGP Address Family Nerd Knobs, I figured out that the BGP Labeled Unicast (BGP-LU, advertising MPLS labels together with BGP prefixes) uses a different address family. So far so good.
Now for the intricate bit: a BGP router might negotiate IPv4 and IPv4-LU address families with a neighbor. Does that mean that it’s advertising every IPv4 prefix twice, once without a label, and once with a label? Should that be the case, how are those prefixes originated and how are they stored in the BGP table?
As always, the correct answer is “it depends”, this time on the network operating system implementation. This blog post describes Cisco IOS behavior, a follow-up one will focus on Arista EOS.

This is just a quick post to share something that I found which is a really nice quality of life tip for VSCode. In this post, I will show you how to configure per-language settings in VSCode so that for example in Python files you can set to indent with 4 spaces and in Javascript you...continue reading

Today, March 22, 2022 at 03:30 UTC we learnt of a compromise of Okta. We use Okta internally for employee identity as part of our authentication stack. We have investigated this compromise carefully and do not believe we have been compromised as a result. We do not use Okta for customer accounts; customers do not need to take any action unless they themselves use Okta.
Our understanding is that during January 2022, hackers outside Okta had access to an Okta support employee’s account and were able to take actions as if they were that employee. In a screenshot shared on social media, a Cloudflare employee’s email address was visible, along with a popup indicating the hacker was posing as an Okta employee and could have initiated a password reset.
We learnt of this incident via Cloudflare’s internal SIRT. SIRT is our Security Incident Response Team and any employee at Cloudflare can alert SIRT to a potential problem. At exactly 03:30 UTC, a Cloudflare employee emailed SIRT with a link to a tweet that had been sent at 03:22 UTC. The tweet indicated that Okta had potentially been breached. Multiple other Cloudflare employees contacted SIRT over the following Continue reading
