The CiscoÂ® CRS-3 Carrier Routing System Essentials (CRS3E) Version 3.0 lab-intensive course introduces you to the Cisco CRS-3 carrier routing system and its features and functions. You will learn the important theoretical concepts on which the Cisco CRS-3 solution is based and gain the practical knowledge and skills to successfully deploy it on 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 IOSÂ® XR Software operating system, deploy the Cisco 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 correct operation of various Cisco 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 Cisco CRS Performance Route Processors (CRS-PRPs), 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.
