  Automating VLAN Creation on Cisco Devices with Ansible Ansible is a powerful automation tool that simplifies network management tasks, including creating VLANs on Cisco devices. For beginners, this guide will walk you through automating VLAN creation step-by-step, from setting up Ansible to deploying VLAN configurations. What is a VLAN? A VLAN (Virtual Local Area Network) is a logical group of devices within a network that can communicate as if they were on the same physical network, regardless of their physical location. VLANs improve network efficiency and security by segmenting traffic. Why Use Ansible for VLAN Automation? Consistency: Avoid manual configuration errors. Efficiency: Configure multiple devices in seconds. Scalability: Manage large-scale networks easily. Flexibility: Supports various Cisco devices and integrates with other tools. Prerequisites Cisco Device Configuration: Ensure your Cisco devices support SSH and are configured to allow Ans...

What is SD-WAN? SD-WAN or Software Defined Wide Area Network (SD-WAN) is a virtual WAN architecture that allows organizations to take advantage of any combination of transport services like MPLS , LTE and broadband Internet - to connect users to applications. An SD-WAN uses a centralized control function to drive traffic securely and intelligently over the WAN . This increases application performance, improving the user experience, increasing business productivity, and reducing IT costs. What Problems Does SD-WAN Solve? 1)  MPLS cost and constraints Multiprotocol label switching (MPLS) has been the main used routing technique of WAN connectivity between enterprise sites, it delivers guaranteed bandwidth, predictable latency, and privacy. Unfortunately it has it’s restrictions 1.1  Cost MPLS is very expensive and may charge enterprises additional expanses. 1.2  Constraints MPLS cannot be installed in all geographic locatio...
