Cisco IOS XR Software Essentials [IOSXRE]

OVERVIEW

The Cisco IOS XR Software Essentials (IOSXRE) course introduces you to the essential features and functions of the Cisco IOS XR Software operating system that powers many Cisco products. Through a combination of lectures and hands-on lab exercises, you will gain an understanding of all major aspects of the operating system including the architecture, installation and upgrade, automatic provisioning, and using the software command-line interface (CLI). You will also learn how to implement essential software services including system security, logging, timing and synchronization, AAA services, and how to use modular QoS. In addition, you will learn how to implement basic routing and forwarding using Multiprotocol Label Switching (MPLS). Finally, you will learn how to implement and use programmability and monitoring features including Simple Network Management Protocol (SNMP), telemetry, process monitoring, and IOS XR programmability.

This course is worth 24 Continuing Education (CE) Credits
