Modern IBGP Design with AddPath and ORR

Nicola Modena created an interesting presentation describing IBGP designs using BGP Additional Paths and Optimal Route Reflection functionality

Hope you’ll enjoy the presentation as much as I did… and make sure you understand potential circular dependencies you might be introducing when running a route reflector as a virtual machine.

Cisco urges software update to thwart counterfeit switches

Cisco is encouraging users of its popular Catalyst 2960X/2960XR switches to upgrade their IOS operating systems in an effort to combat counterfeiting.Because of the pervasiveness of these switches on the gray market, it’s imperative that customers enable the latest software release – IOS release 15.2(7)E4 or later – to validate the authenticity, security, and performance of their Catalyst 2960X/2960XR 24/48 port Gigabit Ethernet switches, Cisco stated in a notice to customers.

The state of cloud-native security 2022 – Tigera’s new market report

We are excited to announce the publication of our first State of Cloud-Native Security market report! The report compiles survey results from more than 300 security and IT professionals worldwide (all of whom have direct container responsibilities), and explores organizations’ needs and challenges when it comes to containers and cloud-native applications, specifically in the areas of security, observability, and compliance.

Report highlights

Our survey results showcase the rise in cloud-native development, while identifying barriers and areas where organizations need support on their cloud-native journey. Some of the report’s key findings include:

Cloud-native applications gain momentum but present security, compliance, and observability issues.
- While our survey found that 75% of companies are focusing development on cloud-native applications, the increased development (and deployment) also creates the need for more advanced observability and security capabilities.
Containers require security solutions for runtime, access, and networking.
- 98% of organizations need container security, with runtime security topping the list.
Cloud-native and container compliance requirements are driving delays and challenges.
- 95% of organizations report they have compliance requirements for cloud-native applications, with 84% stating that meeting these compliance requirements is challenging.

Why read the report?

The report gives organizations a chance to benchmark themselves against the findings, Continue reading

Automating Applications and Servers at the Edge with Red Hat Ansible Automation Platform

Screen Shot 2022-05-03 at 10.32.12 AM

In my previous blog, Why 2022 will be the year for edge automation, we discussed the objective of edge solutions to bring resources closer to the end user or data source.

As edge expands its IT footprint and becomes an extension of the data center, bare-metal, virtual environments, private cloud and public cloud start to coexist as part of the infrastructure.

While our customers move forward with their own automation journey, they are adding edge computing to the puzzle, with common automation challenges such as:

How to automate disparate architectures at scale?

How do we reduce the operational burden, if the IT teams do not grow exponentially?

What is needed to foster a collaborative automation practice?

As part of this blog we will go through a hybrid edge computing automation scenario. But let's start with the fundamental question: Why is hybrid cloud critical for edge computing?

Hybrid cloud to solve edge computing challenges

At the edge, geography matters.

The fundamental need is to allocate resources closer to where the data is generated to pre-process the information before forwarding it to the data centers. The reason for this architectural change is to increase Continue reading

BGP Policy (Part 6)

At the most basic level, there are only three BGP policies: pushing traffic through a specific exit point; pulling traffic through a specific entry point; preventing a remote AS (more than one AS hop away) from transiting your AS to reach a specific destination. In this series I’m going to discuss different reasons for these kinds of policies, and different ways to implement them in interdomain BGP.

In this post I’m going to cover local preference via communities, longer prefix match, and conditional advertisement from the perspective of AS65001 in the following network—

Communities an Local Preference
As noted above, MED is the tool “designed into” BGP for selecting an entrance point into the local AS for specific reachable destinations. MED is not very effective, however, because a route’s preference will always win over MED, and because it is not carried between autonomous systems.
Some operators provide an alternate for MED in the form of communities that set a route’s preference within the AS. For instance, assume 100::/64 is geographically closer to the [65001,65003] link than either of the [65001,65002] links, so AS65001 would prefer traffic destined to 100::/64 enter through AS65003.
In this case, AS65001 can advertise 100::/64 with Continue reading

The deluge of digital attacks against journalists

“A free press can, of course, be good or bad, but, most certainly without freedom, the press will never be anything but bad.”
― Albert Camus

Since its founding in 1993, World Press Freedom Day has been a time to acknowledge the importance of press freedom and call attention to concerted attempts to thwart journalists’ essential work. That mission is also embedded in the foundations of our Project Galileo, which has a goal of protecting free expression online — after the war in Ukraine started, applications to the project increased by 177% in March 2022 alone.

In Uruguay today, UNESCO’s World Press Freedom Day Global Conference is underway, with a 2022 theme of “Journalism under Digital Siege.”

It is a fitting and timely theme.

While the Internet has limitless potential to make every person a publisher, bad actors — both individuals and governments — routinely deploy attacks to silence free expression. For example, Cloudflare data illustrate a trend of increased cyber attacks since the invasion of Ukraine, and journalists are frequent targets. Covering topics such as war, government corruption, and crime makes journalists vulnerable to aggression online and offline. Beyond the issue of cyber attacks, Russian authorities’ Continue reading
