Instead of failing with a hard error when a device lacks support for a required BGP feature, the lab starts with a warning and explanation. This was achieved by adapting a generic plugin originally developed for netlab integration testing, which dynamically adjusts lab topology and validation tests based on the available features of the tested device. The approach was motivated by the need to avoid test failures caused by missing prerequisite features (like VRFs) rather than the actual feature under test. ## Full article daily.dev links to this article rather than hosting it. Read it at the original source: ## Questions this post answers ### How does netlab handle BGP lab exercises when a device doesn't support a required feature? Netlab now starts the lab with a warning and explanation instead of a hard error when a device lacks support for a required BGP feature. A generic plugin adjusts the lab topology and validation tests based on the device's available features — for example, removing routing policies and related validation tests if the device supports BGP route aggregation but not routing policies. _Network engineers building BGP labs with varied device support track netlab changes like this on daily.dev._ ## Similar posts on daily.dev - [BGP-Free Core with SR-MPLS « ipSpace.net blog](https://daily.dev/posts/bgp-free-core-with-sr-mpls-ipspace-net-blog-h7kronzy3) · ipSpace.net Blog · 0 upvotes · 0 comments --- Tags: [#testing](https://daily.dev/tags/testing), [#networking](https://daily.dev/tags/networking), [#bgp](https://daily.dev/tags/bgp) [View this post on daily.dev](https://daily.dev/posts/bgp-labs-graceful-degradation-for-unsupported-devices-ipspace-net-blog-ywqvg64ig) ```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":"BGP Labs: Graceful Degradation for Unsupported Devices « ipSpace.net blog","url":"https://daily.dev/posts/bgp-labs-graceful-degradation-for-unsupported-devices-ipspace-net-blog-ywqvg64ig","mainEntityOfPage":{"@type":"WebPage","@id":"https://daily.dev/posts/bgp-labs-graceful-degradation-for-unsupported-devices-ipspace-net-blog-ywqvg64ig"},"datePublished":"2026-08-11T08:54:32.807Z","dateModified":"2026-08-24T06:59:37.207Z","description":"The BGP labs project (built on netlab) now handles unsupported device configurations more gracefully.
