CCIE Enterprise Infrastructure is the most popular CCIE track, validating expert-level skills in enterprise networking — routing, switching, SD-WAN, and network assurance. The v1.1 lab exam is 8 hours and tests both design reasoning and hands-on configuration across complex multi-protocol topologies.
Exam Overview
The CCIE Enterprise Infrastructure v1.1 exam consists of two modules:
| Module | Duration | Format | Key Focus |
|---|---|---|---|
| Module 1: Design | 3 hours | Scenario-based | Architecture reasoning, no CLI |
| Module 2: Deploy, Operate, Optimize | 5 hours | Hands-on lab | Configuration, troubleshooting, optimization |
Core Exam Domains
| Domain | Weight | Technologies |
|---|---|---|
| Network Infrastructure | 25% | OSPF, EIGRP, BGP, STP, VXLAN |
| SD-WAN | 20% | vManage, overlay design, policies |
| Transport Technologies | 15% | MPLS, GRE, DMVPN, IPsec |
| Infrastructure Security | 15% | AAA, CoPP, uRPF, MACsec |
| Network Assurance | 15% | DNA Center, NetFlow, SNMP, streaming telemetry |
| Automation | 10% | Python, NETCONF, RESTCONF, model-driven programmability |
Who Should Pursue This Track?
CCIE Enterprise Infrastructure is ideal for:
- Network engineers managing campus, WAN, or branch networks
- CCNP Enterprise holders ready to advance to expert level
- Network architects who need to validate design skills alongside hands-on expertise
- Engineers transitioning from traditional routing/switching to SD-WAN and automation
Prerequisites: Strong CCNP Enterprise-level knowledge. Hands-on experience with BGP, OSPF, and at least basic SD-WAN familiarity.
Study Timeline & Preparation Path
Month 1-2: Core Foundations
- BGP path selection, route policies, communities, and confederations
- OSPF multi-area design, NSSA, virtual links, and summarization
- Layer 2: STP (RSTP, MST), VXLAN EVPN fundamentals
- EIGRP stub routing and named mode configuration
Month 3-4: Advanced Topics
- SD-WAN architecture: vManage, vBond, vSmart controller deployment
- SD-WAN policies: centralized control, data, and application-aware routing
- DNA Center network assurance: path trace, client health, AI-driven insights
- Network automation: Python scripting, NETCONF/RESTCONF with IOS-XE
Month 5-6: Exam Readiness
- Full 8-hour mock labs (minimum 4 attempts)
- Design module practice: write architecture justifications for campus, WAN, and DC scenarios
- Speed-config notepad: BGP, OSPF, SD-WAN templates for rapid deployment
- Troubleshooting drills: identify and fix misconfigurations under time pressure
Salary & Career Impact
| Role | Average Salary (US) | With CCIE EI |
|---|---|---|
| Network Engineer | $95,000 | $130,000 |
| Senior Network Engineer | $115,000 | $155,000 |
| Network Architect | $135,000 | $170,000 |
CCIE Enterprise Infrastructure provides the broadest job market of all CCIE tracks. Enterprise networking roles exist in every industry — healthcare, finance, government, tech, and manufacturing. The SD-WAN and automation components make this certification particularly relevant as enterprises migrate from traditional MPLS WANs.
ROI calculation: At a $35,000 average salary increase and typical $5,000-$10,000 total prep cost, CCIE EI pays for itself within the first year.
Lab Environment & Practice
Recommended setup:
- CML Personal ($199/year): Native IOS-XE, IOS-XR, NX-OS images. Best exam-accuracy match. CML vs INE vs GNS3 comparison →
