Routing, switching, SD-WAN, and modern network design
Networking is the most unforgiving discipline in IT. A misconfigured route, a duplicate VLAN, an MTU mismatch, or an asymmetric firewall rule can take down a business in minutes — and the recovery path is rarely a quick rollback. The SoftwareMarketplace.Net networking hub is written for the engineers who carry that responsibility: network architects, network engineers, cloud networking specialists, and the system administrators who own the LAN, the wireless, and the path to the internet.
Our networking coverage spans campus, data center, wide area, and cloud. We publish deep guides to OSPF, BGP, EVPN/VXLAN, segment routing, and the modern fabrics that have replaced traditional spanning tree. We cover Cisco IOS-XE, NX-OS, and Catalyst Center alongside Arista EOS, Juniper Junos, and the major SD-WAN platforms. Cloud networking is treated as a first-class subject — AWS VPCs, Azure Virtual WAN, Google Cloud VPCs, and the hybrid connectivity patterns that connect them to on-premises networks.
Automation is woven through everything we publish. We write tutorials for Ansible, Nornir, and Python network programming with real examples drawn from production environments. Our certification content covers the CCNA and CCNP tracks, the Cisco DevNet program, and the AWS and Azure networking specialties — written by people who hold those certifications and have implemented the underlying technologies.
If you are new to enterprise networking, the beginner guides will get you from cable to configuration in a structured way. If you are designing a greenfield environment, the pillar architecture guides will help you make decisions you will not regret in three years. If you are troubleshooting in production, the troubleshooting guides walk through the diagnostic patterns experienced engineers use.
