The lab configures VLANs, VRFs, IS-IS, OSPF, EIGRP, BGP, MPLS, VXLAN, and EVPN across devices from three vendors. Due to the resource-intensive nature of the setup, a server with 128GB RAM and 32 CPU cores was required, and routers had to be started in batches of eight to avoid timeouts, with the full lab taking 30 minutes to initialize. ## Full article daily.dev links to this article rather than hosting it. Read it at the original source: ## Questions this post answers ### What hardware resources are needed to run a large netlab topology with ~50 routers? A lab with nearly 50 routers and over 50 Linux nodes using multi-vendor devices required a server with 128GB of RAM and 32 CPU cores. Even with that hardware, the lab took 30 minutes to start, and routers had to be launched in batches of eight to prevent CPU overload timeouts. _Engineers scaling up netlab environments track real-world hardware benchmarks like these on daily.dev._ --- Tags: [#networking](https://daily.dev/tags/networking), [#bgp](https://daily.dev/tags/bgp) [View this post on daily.dev](https://daily.dev/posts/cyber-crane-mesh-topology-built-with-netlab-ipspace-net-blog-xeynrfgcx) ```json {"@context":"https://schema.org","@graph":[{"@type":"Organization","@id":"https://daily.dev/#organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180},"sameAs":["https://twitter.com/dailydotdev","https://github.com/dailydotdev","https://www.linkedin.com/company/daily-dev-ltd"]},{"@type":"WebSite","@id":"https://daily.dev/#website","url":"https://daily.dev","name":"daily.dev","publisher":{"@id":"https://daily.dev/#organization"},"potentialAction":{"@type":"SearchAction","target":{"@type":"EntryPoint","urlTemplate":"https://daily.dev/search?q={search_term_string}"},"query-input":"required name=search_term_string"}}]} {"@context":"https://schema.org","@type":"TechArticle","headline":"Cyber Crane Mesh Topology Built with netlab « ipSpace.net blog","url":"https://daily.dev/posts/cyber-crane-mesh-topology-built-with-netlab-ipspace-net-blog-xeynrfgcx","mainEntityOfPage":{"@type":"WebPage","@id":"https://daily.dev/posts/cyber-crane-mesh-topology-built-with-netlab-ipspace-net-blog-xeynrfgcx"},"datePublished":"2026-08-11T08:55:06.663Z","dateModified":"2026-08-11T09:23:58.398Z","description":"Milan Zapletal shared the source code for a large-scale network lab topology built with netlab, featuring nearly 50 routers and over 50 Linux nodes simulating...","image":"https://media.daily.dev/image/upload/s--1KxV4ohY--/f_auto/v1722860400/public/Placeholder%2007","thumbnailUrl":"https://media.daily.dev/image/upload/s--1KxV4ohY--/f_auto/v1722860400/public/Placeholder%2007","isAccessibleForFree":true,"articleSection":"ipSpace.net Blog","inLanguage":"en","publisher":{"@type":"Organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180}},"author":{"@type":"Organization","name":"ipSpace.net Blog","logo":"https://media.daily.dev/image/upload/s--xS7E82MT--/f_auto,q_auto/v1786438303/logos/ipspace?_a=BAMAMicg0","url":"https://daily.dev/sources/ipspace"},"commentCount":0,"discussionUrl":"https://daily.dev/posts/cyber-crane-mesh-topology-built-with-netlab-ipspace-net-blog-xeynrfgcx","interactionStatistic":[{"@type":"InteractionCounter","interactionType":{"@type":"LikeAction"},"userInteractionCount":0},{"@type":"InteractionCounter","interactionType":{"@type":"CommentAction"},"userInteractionCount":0}],"keywords":"networking,bgp","timeRequired":"PT1M"} {"@context":"https://schema.org","@type":"BreadcrumbList","itemListElement":[{"@type":"ListItem","position":1,"name":"Home","item":"https://daily.dev"},{"@type":"ListItem","position":2,"name":"ipSpace.net Blog","item":"https://daily.dev/sources/ipspace"},{"@type":"ListItem","position":3,"name":"Cyber Crane Mesh Topology Built with netlab « ipSpace.net blog"}]} {"@context":"https://schema.org","@type":"FAQPage","@id":"https://daily.dev/posts/cyber-crane-mesh-topology-built-with-netlab-ipspace-net-blog-xeynrfgcx#faq","mainEntity":[{"@type":"Question","name":"What hardware resources are needed to run a large netlab topology with ~50 routers?","acceptedAnswer":{"@type":"Answer","text":"A lab with nearly 50 routers and over 50 Linux nodes using multi-vendor devices required a server with 128GB of RAM and 32 CPU cores.
