The Cisco Certified Internetwork Expert, or CCIE, is a technical certification offered by Cisco Systems. The CCIE certifies the skills required of network engineers to plan, operate and troubleshoot complex, converged network infrastructures on a wide variety of Cisco equipment.
The program is currently divided into six different areas of expertise or “tracks”. The CCIE track in which one becomes certified determines the different aspects of networking technology. One may also choose to pursue multiple CCIE tracks in several different categories of Cisco technology: Routing & Switching, Service Provider, Security, Collaboration, Data Center, and Wireless.
