Building a Small Network with ChatGPT

I must be a good prompt engineer – every time I ask ChatGPT something really simple it spews out nonsense. This time I asked it to build a small network with four routers:

I have a network with four Cisco routers (A,B,C,D). They are connected as follow: A-B, B-C, A-D, D-C. Each router has a loopback interface. Create router configurations that will result in A being able to reach loopback interfaces of all other routers.

Here’s what I got back¹:

Here’s an example configuration for the four routers that should allow Router A to reach the loopback interfaces of all other routers:

Announcing VMware HCX+ Initial Availability

If you had to sum up multi-cloud management in a single word, “complex” would be a fair choice. Although multi-cloud strategies vary from one organization to the next—i.e., some use a mix of public and private clouds while others might use only public or only private infrastructures—all multi-cloud architectures significantly increase the complexity and challenges that IT organizations must navigate.

Today, we’re excited to announce a new offering, HCX+, designed to help mitigate the challenges of thriving in a multi-cloud world. By helping to streamline and accelerate workload migration and mobility between on-premises, public cloud, and private cloud environments, HCX+ simplifies complex processes like data center modernization, hardware refresh, data center consolidation, data center evacuation, cloud migration, data center extension, cloud bursting, and cloud rebalancing.

Keep reading for an overview of the major benefits and features that HCX+ brings to the table.

Announcing HCX+ Initial Availability

HCX+, which is in initial availability as of today, is a SaaS-based workload migration and mobility service from VMware that provides centralized management, orchestration, and observability for migration, repatriation, and rebalancing initiatives across multi-cloud environments.

HCX+ builds on VMware’s existing HCX solution, enabling easier and faster configuration and operability. With HCX+, migration Continue reading

Failed hard drives lasted less than three years, analysis finds

Failed hard disk drives ran for an average of 25,233 hours before their demise, which translates to a lifespan of two years and 10 months.That’s according to Secure Data Recovery, which has a specific perspective on the matter. It specializes in salvaging data from failed hard drives, so pretty much every hard drive that it sees isn’t working properly, which gives it the opportunity to spot some patterns in hard drive longevity. (Secure Data Recovery’s analysis is different from the quarterly hard-drive report from cloud storage vendor Backblaze, which focuses on the few hard drives that fail out of the hundreds of thousands that it uses.)To read this article in full, please click here

Introducing Cloudflare’s new Network Analytics dashboard

We’re pleased to introduce Cloudflare’s new and improved Network Analytics dashboard. It’s now available to Magic Transit and Spectrum customers on the Enterprise plan.

The dashboard provides network operators better visibility into traffic behavior, firewall events, and DDoS attacks as observed across Cloudflare’s global network. Some of the dashboard’s data points include:

1. Top traffic and attack attributes
2. Visibility into DDoS mitigations and Magic Firewall events
3. Detailed packet samples including full packets headers and metadata

This dashboard was the outcome of a full refactoring of our network-layer data logging pipeline. The new data pipeline is decentralized and much more flexible than the previous one — making it more resilient, performant, and scalable for when we add new mitigation systems, introduce new sampling points, and roll out new services. A technical deep-dive blog is coming soon, so stay tuned.

In this blog post, we will demonstrate how the dashboard helps network operators:

1. Understand their network better
2. Respond to DDoS attacks faster
3. Easily generate security reports for peers and managers

Understand your network better

One of the main responsibilities network operators bare is ensuring the operational stability Continue reading

BGP Management with Ansible Validated Content using the network.bgp collection

At AnsibleFest 2022, we announced a new addition to the content ecosystem offered through the platform which is Ansible validated content. Ansible validated content is use cases-focused automation content that is packaged as Collections that contain Ansible plugins, roles and playbooks that you can use as an automation job through Red Hat Ansible Automation Platform.

Now that we understand what Ansible validated content is, we still have  to see what it brings to  network automation practices. We have already talked about a generic Ansible validated content for network automation which is network.base.

Network Border Gateway Protocol (BGP) is more focused  on very specific use cases –  managing BGP resources and neighborship,  platform-agnostic network automation and enhancing the experience of BGP management by providing production ready -content.

 

Network BGP Use Cases

The network.bgp Collection enables users to manage the BGP resources independent of platforms, as well as performing BGP health checks. It includes the following capabilities: 

• Build Brownfield Inventory. The `persist` action enables users to be able to get the BGP global and address family facts  and store it as inventory host_vars. The idea is to have this dynamic inventory as a single source of truth for Continue reading

Internet disruptions overview for Q1 2023

Cloudflare operates in more than 285 cities in over 100 countries, where we interconnect with over 11,500 network providers in order to provide a broad range of services to millions of customers. The breadth of both our network and our customer base provides us with a unique perspective on Internet resilience, enabling us to observe the impact of Internet disruptions.

We entered 2023 with Internet disruptions due to causes that ran the gamut, including several government-directed Internet shutdowns, cyclones, a massive earthquake, power outages, cable cuts, cyberattacks, technical problems, and military action. As we have noted in the past, this post is intended as a summary overview of observed disruptions, and is not an exhaustive or complete list of issues that have occurred during the quarter.

Government directed

Iran

Over the last six-plus months, government-directed Internet shutdowns in Iran have largely been in response to protests over the death of Mahsa Amini while in police custody. While these shutdowns are still occurring in a limited fashion, a notable shutdown observed in January was intended to prevent cheating on academic exams. Internet shutdowns with a similar purpose have been observed across a number of other countries, and have also occurred in Continue reading

Should I Care About RPKI and Internet Routing Security?

One of my subscribers sent me this question:

I’m being asked to enter a working group on RPKI and route origination. I’m doing research, listening to Jeff Tantsura, who seems optimistic about taking steps to improve BGP security vs Geoff Huston, who isn’t as optimistic. Should I recommend to the group that the application security is the better investment?

You need both. RPKI is slowly becoming the baseline of global routing hygiene (like washing hands, only virtual, and done once every blue moon when you get new IP address space or when the certificates expire). More and more Internet Service Providers (including many tier-1 providers) filter RPKI invalids thus preventing the worst cases of unintentional route leaks.
