This three-day course is designed to provide students with the tools required for implementing, monitoring and troubleshooting Layer 3 components in an enterprise network. Detailed coverage of OSPF, BGP, class of service (CoS) and multicast is strongly emphasized. 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.

Audience: Network engineers, technical support personnel, reseller support engineers and others responsible for implementing and/or maintaining the Juniper Networks products covered in this course. This course benefits individuals responsible for configuring and monitoring devices running the Junos OS.
Course Duration: 3 Days
Prerequisites:

Students should have basic networking knowledge and an understanding of the Open Systems Interconnection (OSI) model and the TCP/IP protocol suite. Students should also have working experience with basic routing principles.

Students should also attend the Introduction to the Junos Operating System (IJOS), Junos Routing Essentials (JRE), and Junos Intermediate Routing (JIR) courses prior to attending this class.

Course Objectives:

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

  • Describe OSPF area types and operations
  • Configure various OSPF area types
  • Summarize and restrict routes
  • Describe basic BGP operation
  • Explain the route selection process for BGP
  • Configure advanced options for BGP peers
  • Manipulate BGP attributes using routing policy
  • Describe common routing policies used in the enterprise environment
  • Implement a routing policy for inbound and outbound traffic using BGP
  • Describe the various CoS components and their respective functions
  • Explain the CoS processing along with CoS defaults on SRX Series Services Gateways devices
  • Implement some CoS features in an enterprise environment
  • Identify the components of IP multicast
  • Describe the need for reverse path forwarding (RPF) in multicast
  • Configure and monitor Internet Group Management Protocol (IGMP)
  • Identify common multicast routing protocols
  • Describe rendezvous point (RP) discovery options
  • Configure and monitor Protocol Independent Multicast-Sparse Mode (PIM-SM)
  • Configure and monitor RP discovery mechanisms
