Course Overview

Duration: 5 days
CRS3E - Cisco CRS-3 Carrier Routing System Essentials In this course, you will be introduced to the Cisco CRS-3 Carrier Routing System (CRS) and its features and functions. You will learn the important theoretical concepts on which the Cisco CRS-3 is based and gain the practical knowledge and skills to successfully deploy it in your network. You will be able to determine the right Cisco CRS-3 routing system based on the requirements of your network. In the hands-on labs, you will learn to install the Cisco IOS XR Software operating system, deploy Open Shortest Path First (OSPF) and Internal Border Gateway Protocol (iBGP) routing protocols, and deploy Multiprotocol Label Switching-Label Distribution Protocol (MPLS-LDP) and MPLS Layer 3 VPNs in the classroom environment.

Who Should Attend

  • Network professionals
  • Designers
  • Implementation staff
  • Network operations center personnel
  • Support staff who are involved with the deployment, operations, and maintenance of the Cisco CRS-3 Carrier Routing System and who have not taken the Cisco CRS-1 Essentials course
