The CCIE certification is widely considered to be the highest-level certification in computer networking (and perhaps in all of information technology) and sometimes referred to as "the doctorate of networking".
There are 5 different CCIE tracks:
Routing and Switching is the most popular track, and covers a broad overview of all LAN, WAN and dial access network techniques, such as Ethernet, TCP/IP, OSPF and BGP.
There are only about 400 CCIE Security certification holders worldwide. This track concentrates on network security and covers subjects such as Cisco PIX firewall, IOS security, Wireless LAN, security and many others.
This track focuses on networking in the internet service provider industry. Only about 170 persons worldwide hold this certification. Subjects include optical networks , DSLDSL is a TLA that can stand for # Digital Subscriber Line # Damn Small Linux TLAs., WAN switching, Voice over IPIP Telephony also called Internet telephony is the technology that makes it possible to have a telephone conversation over the Internet or a dedicated Internet Protocol (IP) network instead of dedicated voice transmission lines. This allows the eliminatio, Content Networking and Metro Ethernet . The written exam is composed of 50% of General Knowledge and 50% of the chosen subject.

This track concentrates on voice solutions for the enterprise and includes subjects such as QoS, MGCP, Call Manager (Cisco's VoIP PABX) and Unity, Cisco's Unified MessagingUnified Messaging (or UM is the integration of different streams of messages ( email, Fax, voice, video, etc. into a single in-box, accessible from a variety of different devices. It differs from simple multimedia email in that UM systems typically try to platform.
The latest addition to the CCIE certification tracks is the CCIE Storage Networking track. As the name suggests, this track concentrates on storage networking topics, such as Fibre Channel, iSCSI, FCIP and FICON.
In order to become a CCIE, you need to pass two exams; a written and a lab (each in the specific area of the chosen track.) Half of the written exam questions pertain to general networking knowledge, with the other half focusing specifically on the chosen track. The lab is a grueling, 8-hour exam designed to demonstrate that the candidate not only knows the theory but is also able to practice it. The CCIE lab exam is often considered the hardest exam in the IT industry. Many prospective CCIEs need 2 or more attempts to pass it.
There are no formal prerequisites for the CCIE exam, but Cisco recommends to have at least 3 - 5 years experience in networking before attempting to become a CCIE. It is not necessary to hold CCNA or CCNP certifications.
