LENGTH: 32 Hours (4 dage)

PRICE: kr 21.652,00


Attend the JEX and JIR courses in the same week and save ££s*!

This course combines the two courses JEX - Junos Enterprise Switching and JIR - Junos Intermediate Routing.

Junos Enterprise Switching is a two-day course that provides students with intermediate switching knowledge and configuration examples. This course includes an overview of switching concepts and operations, virtual LANs (VLANs), the Spanning Tree Protocol (STP), port and device security features, and high availability (HA) features.

Junos Intermediate Routing is a two-day course that 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 operating system and in monitoring device operations. This course uses Juniper Networks EX Series Ethernet Switches and Juniper Networks SRX 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.

These courses are intermediate-level.
