Advanced Junos Service Provider Routing

Course ID    :   EDU-JUN-AJSPR

Length    :   Four days

About this Course

This four-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.

  • Implement IS-IS routing policy.
  • Explain the default operation in multiarea IS-IS.
  • Describe IS-IS address summarization methods.
  • Configure and monitor a multiarea IS-IS network.
  • Describe basic BGP operation.
  • List common BGP attributes.
  • 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.
