  • Advanced Junos Service Provider Routing (AJSPR)
    5 days  (Instructor Led Online)  |  Service Provider

    Course Details


    This five-day course is designed to provide students with detailed coverage of OSPF, IS-IS, BGP, and routing policy. Through demonstrations and hands-on labs, students will gain experience in configuring and monitoring the Junos operating system and in monitoring device and protocol operations.


    This course uses Juniper Networks MX Series 3D Universal Edge Routers for the hands-on component, but the lab environment does not preclude the course from being applicable to other Juniper hardware platforms running the Junos OS. This course is based on the Junos OS Release 12.3R3.4.


    Course Level:

    AJSPR is an advanced-level course.


    After successfully completing this course, you should be able to:

    • Describe the various OSPF link-state advertisement (LSA) types.
    • Explain the flooding of LSAs in an OSPF network.
    • Describe the shortest-path-first (SPF) algorithm.
    • List key differences between OSPFv2 and OSPFv3.
    • Describe OSPF area types and operations.
    • Configure various OSPF area types.
    • Summarize and restrict routes.
    • Identify some scenarios in a service provider network that can be solved using routing policy or specific configuration options.
    • Use routing policy and specific configuration options to implement solutions for various scenarios.
    • Explain the concepts and operation of IS-IS.
    • Describe various IS-IS link-state protocol data unit (LSP) types.

    • Explain the route selection process for BGP.
    • Describe how to alter the route selection process.
    • Configure some advanced options for BGP peers.
    • Describe various BGP attributes in detail and explain the operation of those attributes.
    • Manipulate BGP attributes using routing policy.
    • Explain the causes for route instability.
    • Describe the effect of damping on BGP routing.
    • Explain the default behavior of damping on links.
    • Control damping using routing policy.
    • View damped routes using command-line interface (CLI) commands.
    • Describe the operation of BGP route reflection.
    • Configure a route reflector.
    • Describe the operation of a BGP confederation.
    • Configure confederations.
    • Describe peering relationships in a confederation.
