Cisco IOSv in EVE-NG, ready to run

IOSv is already in the Add Node list of every CloudLabBox workspace, so you can drop routers into a lab without uploading an image. Use it for CCNA and CCNP routing practice: static routes, OSPF, EIGRP, BGP, NAT and ACLs.

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.

EVE-NG admits a node by the CPU and RAM set on it, so a running node counts against your plan at these values. This template starts nodes at 1 vCPU and 1,024 MB, which fits the free demo’s 6 vCPU and 8 GB, so you can start one there and open its console.

Multi-area OSPF across four routers

Cable four IOSv routers in a ring, split the links into two OSPF areas and originate a default route from one of them. You practise adjacencies, area border routers, LSA types and summarisation.

The topology saves automatically, but each router keeps its own configuration: run write memory before you stop a node.

  • 4×IOSv vios1 vCPU, 1024 MB each

Added with these defaults, the lab uses 4 vCPU and 4 GB of RAM. The smallest plan that fits is Lite, with 6 vCPU and 8 GB: £3 a day, or £0.50 an hour On-Demand.

Choose a planGive nodes more CPU or RAM and you add that instead.

Licences are yours to bring

Most IOSv images here are Cisco's adventerprisek9 build, the Advanced Enterprise feature set with crypto. CloudLabBox doesn't provide Cisco licences or subscriptions, so anything that needs a Cisco entitlement is yours to bring.

The images run only inside your CloudLabBox workspace; they aren’t available to download.

Guided labs that use IOSv

Ready-made labs in the Shared folder of every lab workspace, each with a scenario, tasks, checks and the full solution. Here are 8 of the 318 that use it, from 24 courses, counted on 2 November 2026.

Questions about IOSv

What is Cisco IOSv?

Cisco IOSv is a virtual router that runs classic Cisco IOS 15. It's the usual router for CCNA and CCNP routing labs: static routes, OSPF, EIGRP, BGP, NAT and ACLs.

Can IOSv routers reach the internet from a lab?

Yes, through CloudLabBox's controlled egress. Connect one IOSv's outside interface to an EVE-NG Bridge network, give it ip address dhcp, route the rest of the lab through it and request each destination from your Account page. Don't add source NAT on the router: CloudLabBox applies NAT after it.

What's the difference between IOSv and IOSvL2?

IOSv is the router and IOSvL2 is the switch from the same family, with VLANs, trunks and spanning tree. Most CCNA labs pair the two, and both are installed.

Which IOSv image should I start with?

The 15.9(3) images are the newest. vios-adventerprisek9-m.spa.159-3.m8 is the one the node tips record reaching its initial configuration dialogue, so it's a safe first choice.

Cisco: which ASAv and IOSv images passed the latest startup checks?

asav-9-20-2 reached the ciscoasa> prompt. vios-adventerprisek9-m.spa.159-3.m8 reached its initial configuration dialogue. In the ASAv profile, the first adapter is Mgmt0/0 and data adapters start at Gi0/0. Use the data adapters for traffic through the firewall.

From the node tips, updated 9 October 2026.

Which IOSv images are installed?

13 images, all listed on this page exactly as Add Node shows them. The newest is vios-adventerprisek9-m.spa.159-3.m9.

How much CPU and RAM does a IOSv node use?

When you add one, the vios template adds 1 vCPU and 1024 MB of RAM. You can change both in Add Node, and your plan counts what each running node is set to.
