Cisco CRS-1 Essentials v3.4 - 5-day Hands-on class
Course Description
This lab-intensive course introduces you to the Cisco® CRS-1 Carrier Routing System and its features and functions. You will learn the important theoretical concepts that the Cisco CRS-1 Routing System is based on as well as gain the practical knowledge and skills to successfully deploy the Cisco CRS-1 Routing System in your network. You will be able to determine the right Cisco CRS-1 Routing System based on the requirements of your network.
This hardware-intensive course provides you with ample opportunity to practice the techniques taught in class with 12 hands-on labs. You will learn to install the Cisco IOS® XR software operating system; create and configure Secure Domain Routers (SDRs); deploy routing protocols like IS-IS, OSPF, and iBGP; implement IP Multicast; and deploy MPLS traffic engineering and MPLS layer 3 virtual private networks (VPNS) in the classroom environment.
You will also use Routing Policy Language (RPL) to learn to deploy large-scale routing configurations and perform basic troubleshooting. This course combines lecture materials and hands-on labs throughout to ensure that you are able to successfully deploy a Cisco CRS-1 Routing System network.
