Enterprise Infrastructure

Building a functional Cisco SD-WAN lab on EVE-NG requires 64GB+ RAM, controller images at version 20.15+, and roughly 3–4 hours of setup time — but it gives you hands-on access to every SD-WAN component tested on the CCIE EI v1.1 lab exam. This is the single most important lab you can build for CCIE Enterprise Infrastructure preparation in 2026. Key Takeaway: SD-WAN covers five full subsections of the CCIE EI v1.1 blueprint (2.2.a through 2.2.e). A properly built EVE-NG lab with vManage, vBond, vSmart, and cEdge devices lets you practice every orchestration, control plane, and data plane scenario the exam throws at you. ...

Cisco just booked $2.1 billion in AI infrastructure orders from hyperscalers in a single quarter — up from $1.3 billion the quarter before. Their networking product orders surged over 20% year-over-year. If you hold a CCIE Enterprise Infrastructure or you’re studying for one, your skills just became significantly more valuable. The “networking is boring” era is officially dead. Key Takeaway: AI workloads are driving the biggest networking investment cycle in a decade, and the protocols tested on the CCIE EI lab — BGP, VXLAN/EVPN, SD-WAN, QoS — are exactly what hyperscalers and enterprises need to build AI-ready infrastructure. ...

The CCIE Enterprise Infrastructure lab exam is one of the most demanding certifications in the networking industry. With a first-attempt pass rate hovering around 20%, most candidates walk in underprepared — and walk out with a failing score. But it doesn’t have to be that way. After years of helping engineers achieve their CCIE on the first attempt, I’ve distilled the strategies that separate first-time passers from repeat takers. This isn’t theory — it’s a battle-tested playbook. ...
