Cisco IOS XR Broadband Network Gateway Implementation and Verification

5 days


The Cisco IOS XR Broadband Network Gateway Implementation and Verification 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 learn how to implement and verify subscriber management functions, including authentication, authorization, accounting of subscriber sessions, address assignment, security, policy management and Quality of Service (QoS).


Individuals involved in the deployment, configuration, operation and maintenance of a Cisco IOS XR Broadband Network Gateway Solution.
