Cisco CRS-3 Carrier Routing System Essentials

Course details

Overview:

The Cisco CRS-3 Carrier Routing System Essentials (CRS3E) 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 troubleshoot and verify proper operation of various CRS-3 hardware, including the 140-Gbps switch fabric, 140-Gbps 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. 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
