In this post, we look at BGP on Junos OS and a typical BGP configuration for the underlay, for a 3-stage Clos fabric. We also introduce BGP unnumbered, which is a great way of building the underlay, without the need of any IP addressing.

Bgp bestpath as-path multipath-relax, why this BGP feature is used?. Let’s understand the case with the topology and I will tell you the real-life use case of the Bgp bestpath as-path multipath-relax feature.
In EBGP Multipath, we have two rules to satisfy the Multipathing requirements.
The number of AS has to be the same across the two paths and the AS number needs to be the same as well.
In the above topology, for the destination prefix, 192.168.0.0/24, we have two paths.
Both of the paths are 2 AS Path Lenght, AS 100, and AS200.
And both of the paths consist of the same ASes, AS 100 and AS 200.
Thus, on the above topology, if we enable EBGP Multipath feature it just works.
We will change the AS number in one of the paths in the below topology and EBGP Multipath will not work.
Let’s remember the rules again. 1: Number of AS Paths 2. AS number in the AS Paths has to be the same.
In the above figure, the number of AS in both of the paths is 2.
But AS numbers are different.
One of the paths: Continue reading
Antonio Boj enjoyed the Cisco ACI webinars by Mario Rosi and sent me this feedback:
I just wanted to pass you my feedback about the documentation and content of the above webinars. Excellent content, very well organized.
My expectation is always high about your content because I’ve become used to it with other webinars you published. I always look for non-marketing content to understand the technology.
I don’t want to criticize vendors based on assumptions or personal agendas from interested people but evaluate whether or not it is the right path forward for the problem I want to solve, knowing the pros and cons. So again, both webinars about Cisco ACI have given me excellent visibility of the solution. Thank you very much!

“It's ridiculous for a country to get all worked up about a game—except the Super Bowl, of course. Now that's important.”
- Andy Rooney, American radio and television writer
When the Super Bowl is on, there are more winners than just one of the teams playing, especially when we look at Internet trends. By now, everyone knows that the Los Angeles Rams won, but we also want to look at which Super Bowl advertisers were the biggest winners, and how traffic to food delivery services, social media and messaging apps, and sports and betting websites changed throughout the game.
We covered some of these questions during our Super Bowl live-tweeting on our Cloudflare Radar account. (Hint: follow us if you’re interested in Internet trends).
Cloudflare Radar uses a variety of sources to provide aggregate information about Internet traffic and attack trends. In this blog post, as we did last year, we use DNS name resolution data to estimate traffic to websites. We can’t see who visited the websites mentioned, or what anyone did on the websites, but DNS can give us an estimate of the interest generated by the ads or across a set of sites in Continue reading
78% of the most popular websites are powered by Linux, which means malware targeting Linux-based operating systems are attacking multi-cloud environments at an alarming rate. Threats such as ransomware, cryptomining components, and remote access tools (RATs) take advantage of weak authentication, vulnerabilities, and misconfigurations in container-based infrastructures. To support IT leaders and cybersecurity professionals in their transformation to top-tier ransomware and malware defense, VMware is proud to sponsor a 1-hour long live webcast on Exposing Threats Lurking in Your Linux-Based Multi-Cloud, on February 28th, at 2 pm ET, presented by SC Media.
In this exclusive partnership with CyberRisk Alliance, our subject matter researchers Giovanni Vigna, Sr. Director of Threat Intelligence, VMware, and Brian Baskin, Technical Lead, Threat Analysis Unit, VMware, explore:
The webinar is an extension of the recently released Exposing Linux-based Threats Lurking in Your Multi-Cloud threat report, which included in-depth research conducted by the VMware Threat Analysis Unit (TAU) on Continue reading
