Network simulator &#8211; Console based: Here you can load any existing lab and try configuration as required using available commands. You can verify the configuration by using TCP\/IP commands such as ping, tracert, and telnet. Several <a href=\"http:\/\/routersimulator.certexams.com\/juniper-sim\/commands_index.htm\">Junos commands<\/a> are available for configuring the devices. All commands are console based, in the sense that you need to type in the commands.<\/p>\n<p>3. Network Simulator &#8211; 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&#8217;t need to remember the syntax, etc.<\/p>\n<p>4. Network Designer: This module is useful for designing your own labs. A screenshot of the same is shown in the figure below:<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"size-medium wp-image-284 alignleft\" src=\"https:\/\/www.certexams.com\/Blog\/wp-content\/uploads\/2018\/03\/juniper-designer-300x226.png\" alt=\"\" width=\"300\" height=\"226\" srcset=\"https:\/\/www.certexams.com\/Blog\/wp-content\/uploads\/2018\/03\/juniper-designer-300x226.png 300w, https:\/\/www.certexams.com\/Blog\/wp-content\/uploads\/2018\/03\/juniper-designer-768x578.png 768w, https:\/\/www.certexams.com\/Blog\/wp-content\/uploads\/2018\/03\/juniper-designer-624x470.png 624w, https:\/\/www.certexams.com\/Blog\/wp-content\/uploads\/2018\/03\/juniper-designer.png 861w\" sizes=\"auto, (max-width: 300px) 100vw, 300px\" \/><\/p>\n<p>As can be seen in the diagram, it consists of two panes. One in the left provides all the devices such as routers, switches, and cables that are available for use. All you need to do is drag and drop the devices as per your requirement and then use appropriate cables to connect those devices. It is recommended that you plan the network diagram beforehand. The design area is given in the right pane of the diagram. The device information is available in the lower pane upon selecting the device (not shown in the diagram here).<\/p>\n<p>5. Network Essentials Manual: This provides networking basics 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.<\/p>\n<p>6. Labs Manual: This manual is called from the Simulator window. Once the simulator window is initiated (eight console-based or GUI based), one can open the labs manual and choose any lab tha<img loading=\"lazy\" decoding=\"async\" class=\"size-medium wp-image-285 alignleft\" src=\"https:\/\/www.certexams.com\/Blog\/wp-content\/uploads\/2018\/03\/juniper-labs-300x248.png\" alt=\"\" width=\"300\" height=\"248\" srcset=\"https:\/\/www.certexams.com\/Blog\/wp-content\/uploads\/2018\/03\/juniper-labs-300x248.png 300w, https:\/\/www.certexams.com\/Blog\/wp-content\/uploads\/2018\/03\/juniper-labs-768x636.png 768w, https:\/\/www.certexams.com\/Blog\/wp-content\/uploads\/2018\/03\/juniper-labs-624x517.png 624w, https:\/\/www.certexams.com\/Blog\/wp-content\/uploads\/2018\/03\/juniper-labs.png 791w\" sizes=\"auto, (max-width: 300px) 100vw, 300px\" \/>t you want to load. After loading the lab into the simulator window, you can work on configuring the same and troubleshooting. The lab manual provides step-by-step instructions on how to configure and troubleshoot the network. Several topics have been covered in the labs so that one need not worry about designing one&#8217;s own labs. The topics covered include labs on router fundamentals, static routing, policies configuration, RIP, OSPF configurations, dynamic routing labs, labs on firewall and NAT configurations, ipv4 and ipv6 configurations, DHCP, VLAN,\u00a0 VTP, and switch configuration labs.
