Introducing MPLS


Description
MPLS networks has become the backbone for modern IP networks, and located at the core of modern service providers. This course covers the basic technologies, along with QoS, TE, and various VPN applications. The course also provides description on the new redundancy and management architectures for the MPLS networks.

Course Objectives
Upon completing the course, the participants will be able to:
Understand MPLS and MPLS VPNs technologies
Describe the architecture & components of MPLS and MPLS VPNs
Explain the use of BGP and modified BGP for MPLS VPNs
Understand how Quality of Service and traffic engineering are delivered using MPLS VPNs
