Several labs have been made available for practice.. Both Command Line Interface (CLI) mode and Graphical User Interface (GUI) mode are available. Domains covered in the labs include

1. Basic IP address configuration of routers and switches

2. RIP, OSPF, DHCP, NAT, Firewall configurations

3. VLAN, VTP configurations

4. STP configuration and troubleshooting

Important features of the Network Simulator software

1. Simulate Juniper J-series routers (J2320, J2350, J4350 and J6350) and M-series routers (M7i and M10i)

2. Simulate Juniper® Junos routers.

3. Support for several router commands

4. Detailed help files

5. Support short form commands. You can type short form commands in Junos simulator.

6. Connectors available are Serial, Ethernet, Sonet, Fast Ethernet, Gigabit Ethernet, E1, T1, T3

7. Network designer that provides drag and drop feature for inserting devices and connectors. GUI based device configurator.

8. Detailed Lab Manual provided.

9. Separate lab manuals given for both the console-based and GUI-based labs.

10. GUI based device configurator.

11. Backup and restore Lab configuration

12. Bookmarking individual Labs or all labs under selected section.

13. Saving and reloading half completed labs

14. Resetting individual and all labs to default.

15. Marking not attempted, not completed and completed labs in different color for easy identification

The Juniper Netsim consists of the following modules:

• Parent framework

• Simulator

  • Console based

  • GUI based

• Network Designer

• Networking Essentials Manual

• Lab Exercise Manual

1. Parent Framework: This is the main window that opens after initiating the software. It contains links to all other modules of the Netsim. A screenshot of the same is shown in the figure below. It consists of four parts, namely,  Network Simulator (Console), Network Simulator (GUI), Network Designer (Dran-drop), and Networking manual.

2. Network simulator – Console based: Here you can load any existing lab and try configuration as required using available commands. You can verify configuration by using TCP/IP commands such as ping, tracert, and telnet. Several Junos commands are available for configuring the devices. All commands are console based, in the sense that you need to type in the commands.

3. Network Simulator – GUI based: Configuring the network is similar to that of console based, but you will have GUI (Graphical User Interface) instead of typing the commands. This way, you don’t need to remember the syntax, etc.

4. Network Designer: This module is useful for designing your own labs. 

5. Network Essentials Manual:This provides basics of networking such as IP addressing, binary to hex conversion, TPC/IP troubleshooting commands, Identifying various connector and cable types, etc. If you are a beginner or intend to review the basics, this manual would be of immense help.

6. Labs Manual: This manual is selected from the Simulator window. Once the simulator window is initiated one can open the lab manual and choose any lab that you want to load. After loading the lab into the simulator window, you can work on configuring the same and troubleshooting
