Overview of the CCIE Routing and Switching v4.0 Written Beta Exam
The Cisco 351-001 CCIE Routing and Switching v4.0 Written Beta targets senior network engineers and architects through an rigorous evaluation of advanced internetworking expertise. Candidates must demonstrate deep proficiency in Layer 2 technologies including STP, VLANs, and frame relay, alongside extensive Layer 3 protocols such as OSPF, EIGRP, BGP, and IS-IS. The assessment mandates architectural mastery of IPv6 transition mechanisms, MPLS VPNs, and complex multicast environments. Furthermore, technical competencies extend to QoS policy implementation, network security hardening, and high-availability design patterns. Mastery of platform-specific management frameworks and diagnostic methodologies remains critical for identifying, mitigating, and troubleshooting complex enterprise routing infrastructures within large-scale multi-protocol network topologies.
