MPLS Fundamentals - Help Prepare you for Exam 642-611 Course

Course Code: TO 146
Course Abstract:

The 642-611 MPLS exam is a qualifying exam for the Cisco Certified Internetwork Professional certification. The 642-611 MPLS exam will test materials covered under the Implementing Cisco MPLS course. The exam will certify that the successful candidate has knowledge and skills necessary to gather information from the technology basics to some of the more updated features and functions such as Traffic Engineering, Fast Reroute and any Transport over MPLS (AToM). The exam covers topics on MPLS Concepts, MPLS Label Assignment and Distribution, Frame-Mode/Cell-Mode MPLS Implementation on Cisco IOS Platforms, MPLS Virtual Private Networks Technology, MPLS VPN Implementation, Complex MPLS VPNs, and Internet Access from a MPLS VPN.

The CCIP (Cisco Certified Internetwork Professional) provides individuals working in service provider organizations with competencies in infrastructure IP networking solutions. CCIP professionals have detailed understanding of networking technologies in the service provider arena including IP routing, IP QoS, BGP, and MPLS.  The 642-611 exam is one of the four core exams required for the Cisco CCIP.
