The Introduction to Cisco IOS XR (IOSXR100) v2.0 is a 4-day instructor-led training or 5-day virtual instructor-led course that introduces you to the features and functions of the Cisco Internetwork Operating System (Cisco IOS) XR Software operating system. You learn the fundamental concepts on which the operating system is based and Cisco IOS XR basic operations, system administration, and troubleshooting. Through a combination of lecture and hands-on lab exercises, you gain an understanding of all major aspects of the operating system, including the architecture, high-availability components, scalability features, configuration basics, basic software operations, configuration file overview, Authentication, Authorization, and Accounting (AAA) services, Network Time Protocol (NTP) configuration, packet filtering, and management plane protection. You also learn how to monitor the Cisco IOS XR operating system, and how to work with error messages and core dumps.

The price in Cisco Learning Credits (CLC) for the IOSXR100 course is 42 CLCs per person.
