What Is Juniper NetSim?
AnandSoft’s Juniper Network Simulator (Juniper NetSim) is a virtual lab tool tailored for individuals preparing for the JNCIA certification (Junos OS). It replicates a real-world Juniper networking environment, allowing users to build, configure, and troubleshoot Juniper-based networks all without physical hardware.
Key Features & Capabilities
Pre-built Lab Exercises
Guided lab scenarios help users practice essential JNCIA topics—ranging from interface configuration to routing protocolsaligning closely with certification objectives.
Authentic Junos OS Simulation
The simulator emulates the Junos OS CLI, delivering an experience true to real Juniper devices. It supports both full and short-form commands for efficient use.
Supports J-Series and M-Series Devices
You can simulate popular Juniper router models like the J2320, J2350, J4350, J6350, M7i, and M10i offering familiarity with devices you’ll likely encounter in exams and day-to-day network operations.
Network Designer (Drag & Drop)
The simulator includes an intuitive topology builder. Users can visually design network layouts by dragging devices and connectors (Ethernet, Serial, SONET, Fast/Gigabit Ethernet, T1/E1/T3) onto the workspace.
Comprehensive Help & Lab Manuals
Integrated documentation and detailed lab manuals support learning and help users troubleshoot commands and configurations on the go.
Lab-Level Features: Connectivity & DHCP
Newer versions enhanced interactivity by enabling communication between hosts and routers/switches and adding DHCP configuration and troubleshooting capabilities.
Advanced Protocol Coverage: VLANs, BGP, VPNs
Updates introduced support for VLANs, BGP routing, VPN scenarios, enabling richer lab scenarios and deeper learning of advanced networking concepts.
ExamSim Integration (Optional)
The enhanced package Cert-Ex™ Network Simulator with ExamSim for JNCIA—combines labs with practice questions (250+), including multiple-choice, drag-n-drop, and simlet types, alongside flashcards and performance tracking.
