Timos-sr-12.0.r6-vm.zip Download [better] May 2026
The Timos-sr-12.0.r6-vm.zip file is a virtual machine archive containing the Nokia (formerly Alcatel-Lucent) Service Router Operating System (SR OS) version 12.0.R6. Specifically, this image is used to emulate the 7750 Service Router (SR) series—a high-performance, edge-routing platform used extensively by service providers for MPLS, Metro Ethernet, and advanced Layer 3 services. Overview of TiMOS SR OS 12.0.R6
The virtual version of this OS, often referred to as a vSim or vSROS, is designed for lab testing, training, and network simulation. Unlike the physical 7750 SR hardware, which uses proprietary application-specific integrated circuits (ASICs), the virtual simulator runs on generic Intel x86 servers using hypervisors like QEMU or VMware.
Functionality: Functional and operational equivalent to hardware-based SR OS routers for control and management planes.
Limitation: It is not intended for production; the forwarding plane is typically capped at 250 packets per second (pps) per interface.
Licensing: Without a valid license file, the VM will usually run for only one hour before automatically reloading. How to Use the Timos-sr-12.0.r6-vm.zip
To use this software, network engineers typically import it into network emulation environments like GNS3 or EVE-NG. Installation Steps for GNS3
Extract the Archive: Unzip TiMOS-SR-12.0.R6-vm.zip to obtain the disk image, typically named sros-vm.qcow2. Add to GNS3: Go to Edit > Preferences > QEMU VMs.
Create a new VM named "Alcatel" and select the sros-vm.qcow2 file as the primary disk (hda). Resource Allocation:
RAM: At least 2048 MB (2 GB) is recommended for stable performance. Network: Configure the adapter type to e1000. Timos-sr-12.0.r6-vm.zip Download
Login Credentials: The default login for this version is typically: Username: admin Password: admin Installation Steps for EVE-NG
Create Directory: SSH into your EVE-NG server and create a folder for the image: mkdir -p /opt/unetlab/addons/qemu/timos-12.0.R6.
Upload & Rename: Upload the sros-vm.qcow2 file and rename it to hda.qcow2 within that directory.
Fix Permissions: Run the command /opt/unetlab/wrappers/unl_wrapper -a fixpermissions to ensure the system can execute the VM. Key Technical Considerations GNS3https://gns3.com Nokia(former ALU) SROS 19 on GNS3 constantly reboots

Virtual 7750 SR Available in 12.0.R4 - Alcatel Unleashed
The file TiMOS-SR-12.0.R6-vm.zip is a virtual image for the Alcatel-Lucent (now Nokia) 7750 Service Router (SR) software, typically used for network simulation in environments like GNS3 or EVE-NG. Official Download Source
Official downloads for TiMOS (SROS) images and documentation are managed by Nokia. Access generally requires a support contract or partner account:
Nokia Support Portal: Use this site to log in and download authorized software releases.
Nokia Documentation Center: You can find official installation and setup guides for the Virtualized Simulator (vSIM) here. GNS3 Integration
If you are trying to use this file in GNS3, you can download the necessary appliance template from the GNS3 Marketplace. The template includes the required MD5 checksums and configurations to recognize the TiMOS-SR-12.0.R6-vm.zip file once you have it. Setup Summary
Once you have downloaded the zip file, follow these typical setup steps for simulation:
Extract: Unzip the file to obtain the virtual disk, usually named sros-vm.qcow2. After extraction, you should see files like:
Import: In GNS3, use the Alcatel 7750 appliance template and point it to your extracted .qcow2 file.
Requirements: This specific 12.0.R6 version typically requires at least 1920 MB to 2048 MB of RAM to run effectively.
Login: The default credentials for the virtualized SR OS are generally admin / admin.
Note: Be cautious with third-party download links found on community blogs or forums. For security and reliability, always prefer the official Nokia/Alcatel-Lucent channels if you have access.
Step 3: Extract the Archive
Use 7-Zip (Windows), The Unarchiver (macOS), or standard unzip (Linux). Double-clicking might not work for large files.
unzip Timos-sr-12.0.r6-vm.zip -d TimosVM/
After extraction, you should see files like:
Timos-sr-12.0.r6.vmdk(virtual hard disk)Timos-sr-12.0.r6.vmx(VM configuration)Timos-sr-12.0.r6.ovf(Open Virtualization Format)
Step 2: Verify Integrity (Optional but Recommended)
If you have a checksum (MD5/SHA256), run:
sha256sum Timos-sr-12.0.r6-vm.zip
Compare the output with the provided hash.
Potential Contents and Uses
- Virtual Machine Image: The
.vmpart suggests the zip file could contain a virtual machine image. This would mean upon extraction and deployment, it could be used to run a specific operating system or software environment directly. - Software for Network Testing/Simulation: If it's related to network testing or simulation, such software could be used to mimic real-world network conditions, allowing users to test network configurations, performance, and resilience.
