Course Content
The Cisco CRS-3 Carrier Routing System Essentials (CRS3E) v1 lab-intensive course introduces you 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. In addition, you will be able to verify proper operation of various CRS-3 hardware, including the 140Gb/s switch fabric, 140Gb/s line cards, 14- and 20-port 10 Gigabit and 1-port 100 Gigabit Ethernet Physical Layer Interface Modules (PLIMs), the Performance Route Processor (PRP), and the new modular power systems, and perform basic troubleshooting. This course combines lecture materials and hands-on labs throughout to make sure that you are able to successfully deploy a Cisco CRS-3 Carrier Routing System network.
