Implementing Cisco Enterprise Advanced Routing and Services (ENARSI)

  • 4.9(45,580 Rating)

Course Overview

The Implementing Cisco Enterprise Advanced Routing and Services (ENARSI) course is designed to provide network professionals with the knowledge necessary to implement and troubleshoot advanced routing technologies and services. This course prepares candidates for the CCNP ENARSI exam, a crucial step towards the CCNP Enterprise certification, and also helps those with a CCNA ENARSI background to advance their skills. Covering a wide range of topics from Layer 3 Technologies, VPN Technologies, and Infrastructure Security, to Infrastructure Services, learners will delve into troubleshooting administrative distance, route maps, and loop prevention mechanisms, and understand complex concepts such as VRF-Lite and Bidirectional Forwarding Detection. The course emphasizes real-world application, ensuring that participants can manage and optimize modern enterprise networks effectively. By completing this course, learners will enhance their professional value and be equipped with the skills needed in today’s networking environments.

Learning Objectives and Outcomes

  • Troubleshoot and understand administrative distance and its impact on routing protocol selection.
  • Apply route maps to control routing updates and policy-based routing for various protocols.
  • Identify and resolve common routing loop issues using mechanisms such as filtering, tagging, and route poisoning.
  • Perform advanced troubleshooting of protocol redistribution and ensure efficient cross-protocol routing.
  • Configure and troubleshoot both manual and automatic route summarization to optimize network scalability.
  • Implement policy-based routing to direct traffic flow based on policies rather than routing protocols.
  • Configure and verify Virtual Routing and Forwarding (VRF-Lite) for network segmentation and path isolation.

Course Prerequisites

To ensure a successful learning experience in the Implementing Cisco Enterprise Advanced Routing and Services (ENARSI) course, participants should have the following minimum prerequisites:

  • Basic understanding of network fundamentals and how devices communicate within a network.
  • Knowledge of basic IP addressing, including subnetting and IP routing concepts.
  • Familiarity with Cisco IOS networking and command-line interface (CLI) configuration.
  • Prior experience with managing network devices, such as switches and routers.
  • Understanding of basic routing protocol operation (e.g., OSPF, EIGRP, and BGP).
  • Completion of the Implementing and Operating Cisco Enterprise Network Core Technologies (ENCOR) training or equivalent knowledge is highly recommended.

These prerequisites will provide the foundational knowledge necessary to grasp the advanced concepts covered in the ENARSI course.
