Junos Intermediate Routing (JIR)

This three-day course provides students with intermediate routing knowledge and configuration examples.

The course includes an overview of protocol-independent routing features, OSPF, IS-IS, BGP, routing policy, IP tunneling, load balancing, high availability (HA) features, VRRP, and IPv6.

Through demonstrations and hands-on labs, students will gain experience in configuring and monitoring Junos OS and monitoring device operations. This course uses Juniper Networks vSRX Series Services Gateways for the hands-on component, but the lab environment does not preclude the course from being applicable to other Juniper hardware platforms running Junos OS. This course is based on Junos OS Release 23.4R1.

Who Should Attend?

Individuals responsible for configuring and monitoring devices running Junos OS

What You'll Learn

Students will learn to,

  • Describe how routes enter a routing table, and how routers choose the best routes for forwarding traffic.
  • Implement static routing within Junos OS.
  • Describe OSPF within Junos OS.
  • Describe how routing policies control what prefixes can enter the routing table and what prefixes can be advertised by protocols.
  • Deploy OSPF within Junos OS.
  • Implement IS-IS within Junos OS.
  • Implement BGP within Junos OS.
  • Deploy BGP within Junos OS.
  • Describe some important advanced routing policy features and behaviors.
  • Implement routing instances within Junos OS.
  • Implement load balancing within Junos OS.
  • Implement VRRP within Junos OS.
  • Implement graceful routing and Bidirectional Forwarding Detection (BFD) within Junos OS.
  • Implement high availability features—GRES, NSR, and unified ISSU— within Junos OS.
  • Implement IP tunneling within Junos OS.
  • Describe IPv6 within Junos OS.
