Day One: Dynamic Subscriber Management

This Day One book introduces you to all the fundamentals of the Juniper Networks Dynamic Subscriber Management solution and shows you how to get it up and running in a day. By the end of the last chapter, you’ll know what is meant by dynamic and why it’s different from legacy approaches that are so prevalent today. You’ll see how Juniper creates a seamless subscriber management interworking between the MX Series, as a BRAS device, and the Juniper Steel-Belted RADIUS (SBR) server. You’ll be introduced to the new MX configuration hierarchies and how they interrelate with existing hierarchies, and you’ll review the SBR administration GUI and learn about creating service definitions.

This book provides hands-on exposure to actual MX configurations, driving the SBR administration GUI, looking through logs, and learning troubleshooting skills that can assist you in product demonstrations, proof-of-concept testing, and network pre-staging integration activities. So roll up your sleeves, get the lab prepped, and let’s knock this one out of the park.
