3. CCIE (Cisco Certified Network Experts)

3. CCIE (Cisco Certified Internetwork Expert)

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.

Step One: CCIE Routing and Switching Written Exam

You must pass the two-hour, written qualification exam, which covers networking concepts and some equipment commands before you are eligible to schedule the lab exam.

CCIE Routing and Switching Written Exam

Exam Number 400-101 CCIE
Associated Certifications CCIE Routing and Switching
Duration 120 Minutes (90 - 110 questions)
Available Languages English
Register Pearson VUE


Step Two: CCIE Routing and Switching Lab Exam

The eight-hour lab exam tests your ability to configure actual equipment and troubleshoot the network in a timed test situation. You must make an initial attempt at the CCIE lab exam within 18-months of passing the CCIE written exam. Candidates who do not pass must reattempt the lab exam within 12 months of their last scored attempt in order for their written exam to remain valid. If you do not pass the lab exam within three years of passing the written exam, you must retake the written exam before being allowed to attempt the lab exam again.

CCIE R&S Lab Exam Overview


Mobile CCIE Labs provide greater access to take your CCIE Routing & Switching Lab exam.

About the CCIE Lab Exam

The CCIE lab exam is an eight-hour, hands-on exam which requires you to configure and troubleshoot a series of complex networks to given specifications. Knowledge of troubleshooting is an important skill and candidates are expected to diagnose and solve issues as part of the CCIE lab exam. You will not configure end-user systems, but are responsible for all devices residing in the network (hubs, etc.). Point values and testing criteria are provided. More detail is found on the Routing and Switching Lab Exam Blueprint and the list of Lab Equipment and IOS Versions.


The Lab Exam cost does not include travel and lodging expenses. Costs may vary due to exchange rates and local taxes (VAT, GST). You are responsible for any fees your financial institution charges to complete the payment transaction. Price not confirmed and is subject to change until full payment is made. For more information on the Lab Exam Registration please reference the Take Your Lab Exam tab.

Lab Environment

The Cisco documentation is available in the lab room, but the exam assumes knowledge of the more common protocols and technologies. The documentation can be navigated using the index. No outside reference materials are permitted in the lab room. You must report any suspected equipment issues to the proctor during the exam; adjustments cannot be made once the exam is over.

Lab Exam Grading

The labs are graded by proctors who ensure that all the criteria have been met. They will use automatic tools to gather data from the routers in order to perform preliminary evaluations.  Candidates must reach a minimum threshold in all three sections and achieve an overall passing score.

Lab Format

The CCIE Routing and Switching Lab exam consists of a 2 hour Troubleshooting section, a 30 minute Diagnostic section, and a 5 hour and 30 minute Configuration section.  Candidates may choose to borrow up to 30 minutes from the Configuration section and use it in the Troubleshooting section.


You can review your lab exam results online (login required), usually within 48 hours. Results are Pass/Fail and failing score reports indicate major topic areas where additional study and preparation may be useful.

Reevaluation of Lab Results

A Reread involves having a second proctor load your configurations into a rack to re-create the test and re-score the entire exam. Rereads are available for the Routing and Switching, and Service Provider technology tracks.

A Review involves having a second proctor verify your answers and any applicable system-generated debug data saved from your exam. Reviews are available for all other tracks.

Payment Terms

Make your request within 14 days following your exam date by using the "Request for Reread" link next to your lab record. A Reread costs $1000.00 USD and a Review costs $400.00 USD. Payment is made online via credit card and your Reread or Review will be initiated upon successful payment. You may not cancel the appeal request once the process has been initiated. Refunds are given only when results change from fail to pass.


The CCIE Routing and Switching Lab exam features a 2 hour troubleshooting section.  Candidates will be presented with a series of trouble tickets for preconfigured networks and need to diagnose and resolve the network fault or faults.  As with the configuration section, the network must be up and running for a candidate to receive credit.  Candidates who finish the troubleshooting section early may proceed on to the diagnostic section, but they will not be allowed to go back to troubleshooting.
