Juniper AJRE Course Overview
This course is an instructor-led course designed to provide enterprise network engineers with the knowledge and skills necessary to use Juniper Networks routers to meet their networks' requirements. It covers advanced routing and services configurations of Juniper Networks J-series and M-series platforms, focusing specifically on advanced configurations commonly used in the enterprise environment.
Objectives
After successfully completing this course, you should be able to:
- Explain how Juniper Networks routers evaluate policies.
- Implement a stateless firewall filter to protect the Routing Engine (RE).
- Implement both an inbound and outbound routing policy for traffic over multiple ISP connections using BGP.
- Monitor and troubleshoot BGP sessions and policy application.
- Successfully transition a network running a distance-vector IGP to use a link-state protocol.
- Configure Layer 2 services, including the Multilink Point-to-Point Protocol (MLPPP), Multilink Frame Relay (MLFR), and the Compressed Real-Time Transport Protocol (CRTP).
- Implement a stateful firewall to enforce a firewall policy.
- Implement Network Address Translation (NAT).
- With a virtual private network (VPN) design, create the VPNs between some combination of J-series and M-series routers.
- Given a class-of-service (CoS) design, configure appropriate CoS policies.
- List two branch-office connectivity solutions and the traffic considerations that apply to each.
- Given a list of technical constraints, implement certain branch-office connectivity solutions.
- Explain the interaction of various configuration elements with CoS configuration.
Intended Audience
The primary audience for this course is network engineers who work in an enterprise environment.
Course Level
This is an advanced-level course.
