SR : Refers to the series (specifically the 7750).
Even in this older version, the vSR supports advanced features like MPLS, VPLS, BGP, and RSVP-TE, making it a staple for those studying for the Nokia Service Routing Certification (SRC) program. ⚠️ Implementation Notes
: The router reboots every 60 minutes or drops line cards.
To run the qcow2 (SR OS) in modern containerized environments like Containerlab, you need (Virtual Routers Network Lab). vrnetlab wraps the QEMU VM in a Docker container, allowing it to be orchestrated like a microservice alongside containers running FRR or SR Linux. This is particularly useful for the nokia_sros kind in Containerlab, which relies on vrnetlab/vr-sros images. Timos-sr-13.0.r4-vm.qcow2
While older than Nokia's current major releases, the 13.0.R4 train remains highly relevant for legacy network studies and classic command-line interface (CLI) training. Complete Feature Parity
Version 13.0 introduces stable carrier-grade routing protocols into a virtual lab environment:
Most engineers aren't launching QEMU commands manually. They are using or EVE-NG . SR : Refers to the series (specifically the 7750)
Virtual routing platforms are essential for modern network engineering, testing, and development. Nokia Service Router Operating System (SR OS) is a major platform in this space. The filename represents a specific virtual disk image used to run Nokia's virtualized router simulator.
To make Timos-sr-13.0.r4-vm.qcow2 functional, it must be integrated into a network emulation platform. Below is the general workflow for the most popular environments. 1. EVE-NG Deployment
Timos-sr-13.0.r4-vm.qcow2 is a virtual disk image file that contains the TiMOS (Timetra Internetworking Operating System) software for Alcatel-Lucent (now Nokia) 7750 Service Routers (SR) and 7950 XRS routers. The file name itself provides valuable information: To run the qcow2 (SR OS) in modern
The file is a virtual disk image for the Nokia (formerly Alcatel-Lucent) 7750 Service Router (SR) virtualized operating system, known as TiMOS . Technical Specifications Operating System : TiMOS (Nokia SR OS) version 13.0.R4 .
: Candidates studying for the Nokia Service Routing Certification (SRC) program use virtual images to practice lab exercises.
