How to Simulate Juniper Networks Devices with Juniper vMX 14.1R1 on VMware, KVM, or GNS3
What is Juniper vMX?
Juniper vMX is a virtual router that runs on top of a hypervisor such as VMware, KVM, or GNS3. It is based on the same operating system (Junos) and software features as the physical routers from Juniper Networks. It allows you to create and run realistic network scenarios using virtual machines instead of physical devices.
Juniper vMX is useful for network engineers, developers, testers, students, and researchers who want to learn, experiment, test, or prototype network solutions using Juniper devices. It can also be used for network automation, orchestration, scaling, migration, or disaster recovery purposes.
Juniper vMX has many features that make it a powerful and flexible virtual router. Some of these features are:
It supports most of the routing protocols and services that are available on physical Juniper routers, such as BGP, OSPF, IS-IS, MPLS, VPNs, QoS, NAT, firewall filters, etc.
It can be deployed on various hypervisors such as VMware ESXi, KVM, or GNS3 with minimal configuration.
It can be integrated with other virtual network devices such as switches, firewalls, load balancers, etc.
It can be managed using the same tools and methods as physical Juniper routers, such as CLI (command-line interface), GUI (graphical user interface), J-Web (web-based interface ), or NETCONF (network configuration protocol).
It can be scaled up or down depending on the network requirements and resources available.
It can be licensed per instance or per bandwidth, depending on the usage and budget.
Juniper vMX has different versions that are released periodically by Juniper Networks. Each version has a specific name and number that indicates the Junos version and the release date. For example, vmx.jinstall.vmx.14.1r1.10.domestic is the file name for the Juniper vMX image that runs Junos 14.1R1.10 and was released in 2014.
The latest version of Juniper vMX as of June 2023 is vmx.jinstall.vmx.21.1r1.11.domestic, which runs Junos 21.1R1.11 and was released in May 2023. You can find the list of all the available versions and their release notes on the Juniper Networks website.
