Course information
Price: EGP 12,609.00
Day(s): 3
Course Code: AJER
Delivery Method: Virtual and Classroom


The Advanced Junos Enterprise Routing (AJER) course is designed to provide students with the tools required for implementing, monitoring, and troubleshooting Layer 3 components in an enterprise network. Detailed coverage of OSPF, Border Gateway Protocol (BGP), class of service (CoS), and multicast is strongly emphasized. Through demonstrations and hands-on labs , students will gain experience in configuring and monitoring the Junos operating system and in monitoring device and protocol operations


The knowledge and skills that a learner must have before attending this course are as follows:

  • Basic networking knowledge and an understanding of the Open Systems Interconnection (OSI) model and the TCP/IP protocol suite. Students should also have working experience with basic routing principles.

To gain the prerequisite skills and knowledge,Juniper strongly recommends the knowledge of the following courses:

  • Junos Operating System (IJOS)
  • Junos Routing Essentials (JRE)
  • Junos Intermediate Routing (JIR)
