SPCOR Exam Experience by Nick Russo
On 31 October 2023, I took and passed the Implementing and Operating Cisco Service Provider Network Core Technologies (SPCOR) exam on my first attempt. Most of you know that I am recognized as an expert on Cisco Service Provider technologies given that I was one of the first to pass the new CCIE SPv4 exam in early 2016. Three months later, I released book of nearly 3,000 pages detailing all the technologies involved in that blueprint, going extremely deep into every topic. I later partnered with two other Service Provider experts to sell an ultimate study bundle that combined my textbook with their lab workbook. I think it’s fair to say that I should have crushed this exam, and although I did pass, it was far more difficult than I anticipated.
A few years ago, I also took the SCOR exam, but didn’t write a blog about it because I felt the exam was unremarkable. My friend Craig Stansbury has an excellent SCOR learning path at Pluralsight that I used to pass the exam on the first try, but on balance, it felt like a regular CCNP exam. SPCOR was a whole new class of difficulty. When I Continue reading

How We Measure: RPKI ROA Signing and Route Origination Validation
t APNIC Labs we publish a number of measurements of the deployment of various technologies that are being adopted on the Internet. Here we will look at how we measure the adoption of the signing of Route Origination Attestations (ROAs) as part of the framework for securing inter-domain routing on the Internet using the digital credential framework provided by the Resource Public Key Infrastructure (RPKI).How We Measure: DNSSEC Validation

D2C219: Building A Multi-Cloud Network With A Cloud-Native Approach (Sponsored)
What if you could have a multi-cloud network that was cloud-native, but you didn’t have to know the nitty-gritty details for each of the clouds? That is, you work with a cloud network interface, and that platform handles the networking–in a cloud-native way–for you. You wouldn’t need to know the nuances of AWS, Azure, and...

What if you could have a multi-cloud network that was cloud-native, but you didn’t have to know the nitty-gritty details for each of the clouds? That is, you work with a single cloud network interface, and that platform handles the networking so you can focus on things like improving the velocity of application rollouts, architecture, security, and efficiency? Sponsor Prosimo says its platform can do this. On today's show we look under hood to get details on its multi-cloud networking platform.

Open BGP Daemons: There’s So Many of Them
A while ago, the Networking Notes blog published a link to my “Will Network Devices Reject BGP Sessions from Unknown Sources?” blog post with a hint: use Shodan to find how many BGP routers accept a TCP session from anyone on the Internet.
The results are appalling: you can open a TCP session on port 179 with over 3 million IP addresses.

AI Is Making Data Cost Too Much
You may recall that I wrote a piece almost six years ago comparing big data to nuclear power. Part of the purpose of that piece was to knock the wind out of the “data is oil” comparisons that were so popular. Today’s landscape is totally different now thanks to the shifts that the IT industry has undergone in the past few years. I now believe that AI is going to cause a massive amount of wealth transfer away from the AI companies and cause startup economics to shift.
Can AI Really Work for Enterprises?
In this episode of Packet Pushers, Greg Ferro and Brad Casemore debate a lot of topics around the future of networking. One of the things that Brad brought up that Greg pointed out is that data being used for AI algorithm training is being stored in the cloud. That massive amount of data is sitting there waiting to be used between training runs and it’s costing some AI startups a fortune in cloud costs.
AI algorithms need to be trained to be useful. When someone uses ChatGPT to write a term paper or ask nonsensical questions you’re using the output of the GPT training run. Continue reading
How Data Center Infrastructures Must Change to Support AI
How are enterprises big and small adapting their data center infrastructure to handle AI workloads?5 use cases for automating your infrastructure with Ansible Automation Platform
Infrastructure automation is an area where systems administrators and IT operations teams can see some of the biggest benefits from automation, including time savings, reducing tedious manual work, and improving the overall health of their systems. In this blog, I've identified the top 5 infrastructure automation use cases for Ansible Automation Platform that you can deploy in your own environment, and I've incorporated new capabilities like Event-Driven Ansible to make managing your infrastructure even easier.
- Provisioning Red Hat Enterprise Linux with Ansible Automation Platform
Before you get started with any automation project, we typically recommend using automation analytics to plan and predict the potential cost savings to help prioritize which automation projects will deliver the biggest time and cost savings.
Then you can use Ansible Automation Platform to create a workflow to build or configure a cloud or datacenter instance for RHEL, while using surveys to gather additional user input to enable further customization to meet any system requirements. You can even introduce an IT service management ticketing option, then review the job success and confirm service availability.
