Cisco Certified Internetwork Expert Routing and Switching (CCIE Routing and Switching) certifies the skills required of expert-level network engineers to plan, operate and troubleshoot complex, converged network infrastructure.
There are no formal prerequisites for CCIE certification. Other professional certifications or training courses are not required. Instead, candidates must first pass a written qualification exam and then the corresponding hands-on lab exam. You are expected to have an in-depth understanding of the topics in the exam blueprints and strongly encouraged to have three to five years of job experience before attempting certification.
