Junos Intermediate Routing (JIR)


LENGTH: 16 Hours (2 days)

PRICE: £1,495.00


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

The course includes an overview of protocol-independent routing features, load balancing and filter-based forwarding, OSPF, BGP, IP tunneling, and high availability (HA) features.

Through demonstrations and hands-on labs, students will gain experience in configuring and monitoring the 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 the Junos OS.

This course is based on Junos OS Release 21.1R1.11.
