Course Overview

Top

Multiprotocol Label Switching (MPLS) is a high-performance method for forwarding packets through a network enabling routers at the edge of a network to apply simple labels to packets. This practice allows the edge devices to switch packets according to labels, with minimal lookup overhead. MPLS integrates the performance and traffic-management capabilities of data link Layer 2 with the scalability and flexibility of network Layer 3 routing.

This course covers both introductory and advanced MPLS and MPLS VPNs concepts. Configuration, implementation and troubleshooting skills are all included with a significnat focus on the use of labs to consolidate the learners knowledge. At the end of this course you should be able to design, implement and maintain core IP routing network infrastructures.

Each student will have their own virtual pod of equipment with access to the labs 24x7 for 90 days

This course is worth 40 Credits in the Continuing Education Program
