In order to Isolate a vpn from other vpn we should use vpn Membership in Topology section of vmanage. VPN membership (Who receives routes, it is route visibility control with filtering for Segmentation).This determines which VPN routes are advertised to which sites. [helps define who can join which VPN and who can learn its routes.] It…

In this lab, I am using the Cisco SD-WAN Sandbox environment to build and test a Hub-and-Spoke topology. By default, Cisco SD-WAN allows sites to exchange routes dynamically and build direct communication paths between branches.However, in many enterprise environments, this is not always the desired design. Here is the topology: In my scenario, I want…

When working with Cisco SD-WAN, one of the first real challenges engineers face is onboarding devices—especially understanding the differences between vEdge (Viptela OS) and cEdge (IOS-XE SD-WAN). At first glance, both follow a similar process. But in practice, there are important differences in behavior, commands, and even mindset. In this post, I’ll walk through the…

In this lab project, I built an AI-powered network assistant that: The Idea Instead of manually running commands like: show ip interface briefshow interface Gi0/1show logging | include BGP We can simply ask: The AI determines the required CLI commands, executes them safely, analyzes the results, and provides structured conclusions. The workflow looks like this:…

In this post, I’ll walk through several small but powerful Ansible playbook examples.Each example focuses on a specific concept such as variables, loops, conditions, filters, lookups, and facts. These are small puzzle pieces — but together they form the foundation of automation. Variables in a Playbook + Filters It defines a variable directly inside the…
