The Cisco IOS XR Broadband Network Gateway Implementation and Verification (IOSXR304) v1.0 course teaches you how to successfully deploy, configure, operate, maintain, and support a Cisco IOS® XR Broadband Network Gateway (BNG) solution. This course will show you how to implement and verify BNG on a Cisco IOS XR device to manage subscriber access. You will also learn how to implement and verify subscriber management functions, including authentication, authorization, and accounting of subscriber sessions, address assignment, security, policy management, and Quality of Service (QoS).

This course will help you:

  • Prepare to deploy, implement, configure, operate, and maintain a Cisco IOS XR BNG solution
  • Gain hands-on practice using BNG with lab exercises
  • Deepen your understanding of the Cisco IOS XR BNG solution

Who should enroll

  • System installers
  • System integrators
  • System administrators
  • Network administrators
  • Solution designers


After taking this course, you should be able to:

  • Describe the architecture and function of the Cisco IOS XR Broadband Network Gateway
  • Configure and verify Authentication, Authorization, and Accounting (AAA) in a Broadband Network Gateway deployment
  • Define policies to control subscriber traffic
  • Establish and verify subscriber sessions
  • Prioritize subscriber traffic using QoS
  • Implement subscriber features
  • Deploy redundancy for subscriber sessions


Before taking this course, you should have the following knowledge and skills:
