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
