A practical roadmap focused on hands-on networking skills — configuring IP addressing, routing, switching, VPNs, and wireless networks, then securing, automating, and observing them in production.
Linux and the command line are used throughout this roadmap — from configuring interfaces to running network diagnostics.
A reference to follow when implementing a real network project.
Network Engineering is the foundational discipline that connects systems, users, applications, and clouds across global digital infrastructure. Network engineers design high-availability local and wide-area networks, configure carrier-grade routing protocols, enforce enterprise perimeter security, and automate network fleet operations.
This roadmap covers the complete network engineering skill set: binary subnetting, VLAN switching, OSPF and BGP dynamic routing, IPsec VPN encryption, Python network automation, EVPN-VXLAN data center fabrics, and hybrid cloud interconnects.
Master IPv4/IPv6 VLSM subnetting, OSI model troubleshooting, Cisco IOS switch configuration, VLAN trunking (802.1Q), STP, and Wireshark packet captures.
Key competencies:
Configure dynamic routing protocols (OSPF, BGP), deploy secure IPsec site-to-site VPNs, and automate fleet configurations with Python (Netmiko) and Ansible.
Key competencies:
Architect EVPN-VXLAN spine-and-leaf data center fabrics, manage internet exchange BGP peering, design SD-WAN overlays, and connect hybrid clouds (AWS Direct Connect).
Key competencies:
Yes. The Cisco Certified Network Associate (CCNA) remains the most universally recognized and respected foundational credential in the networking industry, validating hands-on routing, switching, IP services, and security fundamentals.
OSPF (Open Shortest Path First) is an Interior Gateway Protocol (IGP) designed for high-speed, link-state routing inside a single corporate or campus network. BGP (Border Gateway Protocol) is an Exterior Gateway Protocol (EGP) designed for path-vector routing across autonomous systems on the global internet.
Modern enterprise networks contain hundreds or thousands of devices. Configuring switches manually via CLI is error-prone and unscalable. Python (with libraries like Netmiko, Nornir, and Scrapli) enables network engineers to automate configuration deploys, run compliance audits, and interact with REST APIs on modern SDN controllers.
EVPN-VXLAN is the modern standard for data center network architecture. It encapsulates Layer 2 Ethernet frames inside Layer 3 UDP packets (VXLAN overlay) using MP-BGP EVPN as the control plane, eliminating Spanning Tree bottlenecks and allowing seamless virtual machine mobility.
