vJunos-router and vJunos-switch in EVE-NG
Juniper's single-node lab images of an MX router and an EX switch are both waiting in Add Node when you sign in to your CloudLabBox workspace. Practise routing and switching in the same Junos CLI, one node per device.

Add it to a lab
In Add Node, choose the template, then the image. The template fills in these settings; change them before you start the node.
| Image | Template | CPU | RAM | Interfaces | Console |
|---|---|---|---|---|---|
| vJunos-router | vjunosrouter | 4 | 6144 MB | 11 interfaces | telnet |
| vJunos-switch | vjunosswitch | 4 | 16384 MB | 11 interfaces | telnet |
EVE-NG admits a node by the CPU and RAM set on it, so a running node counts against your plan at these values. The largest of these templates starts nodes at 4 vCPU and 16,384 MB, more than the free demo’s 6 vCPU and 8 GB, so use the demo to find the image and a plan to run it.
Two vJunos routers and an EX access switch
Run OSPF and iBGP between two vJunos-routers, then hang a vJunos-switch off one of them with access VLANs and an IRB interface for each.
vJunos-switch is the heavier of the two: its template adds 4 vCPU and 16384 MB, against 4 vCPU and 6144 MB for vJunos-router.

Added with these defaults, the lab uses 12 vCPU and 28 GB of RAM. The smallest plan that fits is Professional, with 18 vCPU and 32 GB: £7.50 a day, or £2 an hour On-Demand.
Licences are yours to bring

Questions about vJunos-router and vJunos-switch
What are Juniper vJunos-router and vJunos-switch?
vJunos-router and vJunos-switch are Juniper's single-VM lab images of an MX router and an EX switch. Both run Junos, so they suit routing, switching and EVPN-VXLAN practice.
Should I use vJunos-router or vMX?
vJunos-router is one node; a vMX is a VCP and a VFP. Both come to 4 vCPU and 6144 MB per router, so the choice comes down to the Junos release you need: vJunos-router covers 23.4 and 24.2, and vMX runs from 16.1 to 24.4.
Which interfaces does vJunos-switch use?
Its template adds 11 interfaces: fxp0 for management, then ge-0/0/0 to ge-0/0/9 for data. vJunos-router uses the same layout.
Which vJunos-router and vJunos-switch images are installed?
6 images (2 vJunos-router, 4 vJunos-switch), all listed on this page exactly as Add Node shows them. The newest is vjunosrouter-24.2R1-S2.5.
How much CPU and RAM does a vJunos-router and vJunos-switch node use?
When you add one, the vjunosrouter template adds 4 vCPU and 6144 MB of RAM; the vjunosswitch template adds 4 vCPU and 16384 MB of RAM. You can change both in Add Node, and your plan counts what each running node is set to.
