Description

The Implementing Cisco Service Provider Next-Generation Core Network Services (SPCORE) v1.2 course is designed to help students prepare for Cisco CCNP SP certification. The SPCORE course is a component of the CCNP SP curriculum.

The SPCORE course introduces the concepts of MPLS and describes its implementation as well as exploring the MPLS TE services built on the MPLS technology. MPLS is a high-performance method for forwarding packets through a network and enables routers at the edge of a network to apply simple labels to packets. This practice allows the core devicestypically the routers in the center of the service provider coreto forward packets according to labels, with minimal lookup overhead. The course also enables learners to use the technology principles of basic QoS, and QoS with MPLS to implement advanced features and functions. The focus of the course is on technology issues of MPLS and on best practices for implementing QoS from the service providers perspective and how to configure some of those features and functions in an existing routed environment.

The course also includes classroom activities with remote labs that are useful to gain practical skills on deploying Cisco IOS or IOS XE and Cisco IOS XR features to operate and support service provider core network services.

Objectives

After completing this course the student should be able to:

  • Describe the features of MPLS, and how MPLS labels are assigned and distributed
  • Discuss the requirement for traffic engineering in modern networks that must attain optimal resource utilization
  • Describe the concept of QoS and explain the need to implement QoS
  • Classify and mark network traffic to implement an administrative policy requiring QoS
  • Compare the different Cisco QoS queuing mechanisms that are used to manage network congestion
  • Explain the concept of traffic policing and shaping, including token bucket, dual token bucket, and dual-rate policing
