Course Description

Multiprotocol Label Switching integrates the performance and traffic-management capabilities of data link Layer 2 with the scalability and flexibility of network Layer 3 routing. So, when used in conjunction with other standard technologies, MPLS gives the ability to support value-added features and service offerings.

Implementing Cisco MPLS (MPLS) v4.0 is a 5-day instructor-led class providing students with in-depth knowledge of MPLS and MPLS VPNs design, implementation and configuration skills for new features and functions in an existing routed environment.  This class uses IoS (15.2)
