Course Content
This three-day course is designed to provide you 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, you will gain experience in configuring and monitoring the Junos operating system and in monitoring device and protocol operations.
Certification: JNCIP-ENT - JN0-643
Who should attend
- Individuals responsible for configuring and monitoring devices running the Junos OS.
