Bgp bestpath as-path multipath-relax
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
BGP Multipath
BGP Multipath – By default installs only a single path in IBGP and EBGP deployment.If prefixes are learned via multiple paths, BGP supports multipath for IBGP, EBGP, or across both IBGP and EBGP via EIBGP Multipath feature. In this blog post, we will explore each of these options: IBGP Multipath, EBGP Multipath, and EIBGP Multipath.
First of all, we should know that BGP Multipath feature should be enabled manually on the network device, unlike IGP protocols.
In IGP Protocols, when there is Multipath, commonly referred to as ECMP (Equal Cost Multipath), Routers install all next-hops for the destination prefixes, to the routing and forwarding table automatically, without manual human operation.
We have on the website, the most detailed , Design and Practial Hands-on BGP Training in the world.
Let’s start with the first EBGP Multipath:
Figure – EBGP Multipath
We have two rules for EBGP Multipath.
1. For the destination prefix, if there is more than one path, total number of AS – Autonomous System should be same across different paths
2. For the destination prefix, if there is more than one path, same AS numbers should be in the AS Path.
On the above figure, since from Continue reading
Feedback: Cisco ACI Webinars
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!

Who won Super Bowl LVI? A look at Internet traffic during the big game
“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
Learn About the Threats Lurking in Your Linux-Based Multi-Cloud
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:
- Existing characterization techniques and how to safeguard against sophisticated malware
- Ransomware and cryptominer power players that target Linux systems following cross-pollination and evolution
- How to fight back against these threats with a combination of approaches, policies, and mechanisms
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

UDP vs TCP for real-time streaming telemetry
Summary of the AWS Service Event in the Northern Virginia (US-EAST-1) Region, "This congestion immediately impacted the availability of real-time monitoring data for our internal operations teams, which impaired their ability to find the source of congestion and resolve it." December 10th, 2021
The data in these charts was created using Mininet to simulate packet loss in a simple network. If you are interested in replicating these results, Multipass describes how to run Mininet on your laptop.
sudo mn --link tc,loss=5
For example, the above command simulates a simple network consisting of two hosts connected by a switch. A packet loss rate of 5% is configured for each link.
Simple Python scripts running on the simulated hosts were used to simulate transfer of network telemetry.

Ansible Automation Platform – A video tour
Many people are familiar with the community version of Ansible, the command line automation tool, but I wanted to elaborate on how our enterprise offering, Red Hat Ansible Automation Platform, and how it expands the possibilities of Ansible for our customers in Red Hat's most recent release.
