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.

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 of the CCIE lab exam within 18-months of passing the CCIE written exam. 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.


Key Benefits of VTP Version 3

Much work has gone into improving the usability of VTP version 3 in three major areas:

• The new version of VTP offers better administrative control over which device is allowed to update other devices' view of the VLAN topology. The chance of unintended and disruptive changes is significantly reduced, and availability is increased. The reduced risk of unintended changes will ease the change process and help speed deployment.

• Functionality for the VLAN environment has been significantly expanded. Two enhancements are most beneficial for today's networks:

– In addition to supporting the earlier ISL VLAN range from 1 to 1001, the new version supports the whole IEEE 802.1Q VLAN range up to 4095.

– In addition to supporting the concept of normal VLANs, VTP version 3 can transfer information regarding Private VLAN (PVLAN) structures.

• The third area of major improvement is support for databases other than VLAN (for example, MST).

EIGRP Wide Metrics and Diagnostics
by INE: As more IPv4 addressing space is handed out and more networks are still cropping up and need addressing, we’ll take a look at how IPv6 can solve those scaling issues. Starting off with how IPv6 works, and its addressing differences we’ll dive right into getting IPv6 working with all the IGPs, BGP, DMVPN and MPLS so that no matter what issues you run into you’ll have a solution available.
