Simplifying OcNOS Configuration Backups With Ansible
Configuration Backups Configuration backups are an important topic for any network operations team, whether it be a service provider or an enterprise IT system. There are various ways to do this, ranging from off-the-shelf products to built-in tools (in the case of VMs), depending on what systems you use. It’s not surprising that this comes […]

OcNOS in Containerlab – Part 2: Platform Analysis for Linux, Windows, and MacOS
If you’re building labs with Containerlab, you’ve probably run into the same platform challenges I have. My previous guide, Containerlab + OcNOS home lab, focused on a budget-friendly Linux mini-PC. Since publishing that, I’ve fielded questions from readers about Mac support, Windows workflows, and hybrid setups like WSL2 or Colima. Over the July 4th weekend, […]

Flex-Algo in OcNOS: Optimizing Network Paths Using Link Delay
In our last blog, we introduced Flexible Algorithms (Flex-Algo) and how TE-metric empowers networks to steer traffic intelligently, much like planning a delivery route based on road capacity, congestion, or cost. We showed how businesses can prioritize critical services like video conferencing over bulk data transfers, using custom traffic engineering values. Now, let’s take the […]

Flex-Algo In OcNOS: Optimizing Network Paths Using TE-Metric
In today’s digital world, network traffic is like city traffic i.e. some roads are faster, some are more reliable, and some should be avoided during peak hours. Just like how a GPS chooses the best route based on distance, time, or road conditions, networks also need to choose the best path for data to travel. […]

Building A Budget OcNOS Lab With ContainerLab
Introduction As someone experimenting with open networking, I wanted a low-cost way to get hands-on with IP Infusion’s OcNOS — without a rack of hardware. My goal was simple: get OcNOS running with ContainerLab in a home setup that anyone could replicate, ideally for under $400. This blog documents the hardware and software choices I […]

Flex-Algo In OcNOS: Fundamentals Of Customized Path Selection
In traditional IGP-based routing, shortest path selection is dictated by link metrics, often leading to suboptimal path choices in certain network scenarios. Segment Routing Flexible Algorithm (Flex-Algo) enables network operators to define customized routing policies based on application needs, optimizing traffic flow while leveraging the scalability of Segment Routing (SR). This blog delves into the […]

EVPN-L3VPN Over ISIS-SR And TI-LFA
EVPN L3VPN leverages the BGP control plane to provide Layer 3 connectivity between different sites over the network infrastructure. It enables IP routing between customer sites, allowing for the seamless exchange of IP packets across a service provider’s network. This approach combines the benefits of traditional MPLS Layer 3 VPNs with the advanced features of […]
