This page will show you the physical WAN, LAN and Switching topologies used by all labs published by Junos Workbook. Please note that the majority of the website was originally developed using the Juniper J2320 Series Routers and EX3200 24 port Series switches however most labs (excluding switching) can be completed using Junos Firefly 12.1X46-D10.2 on VMWare Workstation
The majority of the labs published by Junos Workbook were created using real Juniper Networks hardware. Due to the price of Juniper Networks hardware most of the labs published by Junos Workbook can be reproduced using Olive and Junos Firefly (vSRX) however you should note that ethernet-switching is not supported on Juniper vSRX.
The Junos Workbook topology is build around J2320 Series routers and EX3200 Series switches. Even though the J Series is end of life, they will still run the same operating system as other Juniper hardware. Consider Cisco hardware for example, the 2600 Series routers have been EOL/EOS for many years however they are used in countless classrooms around the world to teach students Cisco IOS. The same can be said about the Junos Software.
The Junos Workbook labs are published running Junos 12.1 which as of current (Jan 2014) is what you’ll be tested on in the Juniper Certifications exams.
Our topology consist of four Juniper J2320 Series Routers and four Juniper EX3200-24 Port Series Switches all devices running 12.1 Junos Software.
For those of you who wish to build the same lab, at the current market cost (Jan 2014) this lab is estimated to be $5,000 USD.
The following table is a list Juniper Networks hardware used by Junos Workbook Topologies:
|Device Name||Device Model||Total Memory||Ethernet Interfaces||PIM Modules||Software|
|R1||Juniper J2320||1GB||4x Gigabit Ethernet||1x JX-2T1-RJ48-S PIM||Junos 12.1X44-D45.2|
|R2||Juniper J2320||1GB||4x Gigabit Ethernet||1x JX-2T1-RJ48-S PIM||Junos 12.1X44-D45.2|
|R3||Juniper J2320||1GB||4x Gigabit Ethernet||1x JX-2T1-RJ48-S PIM||Junos 12.1X44-D45.2|
|R4||Juniper J2320||1GB||4x Gigabit Ethernet||1x JX-2T1-RJ48-S PIM||Junos 12.1X44-D45.2|
|SW1||Juniper EX3200-24T||Fixed 512MB||24x Gigabit Ethernet||Not Applicable||Junos 12.3R9.4|
|SW2||Juniper EX3200-24T||Fixed 512MB||24x Gigabit Ethernet||Not Applicable||Junos 12.3R9.4|
|SW3||Juniper EX3200-24T||Fixed 512MB||24x Gigabit Ethernet||Not Applicable||Junos 12.3R9.4|

This topology is used in WAN Configuration labs found in the JNCIS Workbook. The WAN topology consist of four Juniper J2320 Series Routers each with a single JX-2T1-RJ48-S PIM module installed in slot1. The topology is used to educate engineers on legacy Frame Relay, PPP, MLPPP and T1 circuit configurations which are still commonly used in locations where Ethernet connectivity is unavailable such as gas stations, convenience stores, small branch locations and so on.
The WAN Topology is cabled in a simple ring topology using T1 Cat5e crossovers’ as depicted below;

The Ethernet topology is used throughout several labs published on the Junos Workbook website. This topology depicts all Ethernet connectivity from the Juniper J2320 Series routers to the Juniper EX3200 Series switches.
|Local Router||Local Interface||Remote Switch||Switch Port|
This switching topology shows all the inter-switch link connections between the four switches in the lab. This topology is build using crossovers and is primarly used in the Switching section of the JNCIA-ENT workbook however all router Ethernet connectivity depend on the physical and logical switching topology to be correctly cabled and configured.

The vSRX topology is a virtual topology built within VMWare Workstation using LAN Segments. Four LAN segments provide a full mesh network architecture for the vSRX Platforms giving you the capability to perform some of the labs published by this website. You should note however that vSRX does not support ethernet-switching and T1 line cards therefore can only be used for labs that do not require ethernet-switching and legacy T1 capabilities. Labs such as RIP, OSPF, Static Routing, IP Services, IPv6 and others can all be completed using the vSRX topology.
In order to build the vSRX Topology you must first download the OVA from Juniper. The file name to search for is junos-vsrx-12.1X46-D10.2-domestic.ova
