L3VPNs require weeks of configuration negotiation with service providers and are difficult to automate, while L2VPNs require only a few parameters and can be connected immediately, enabling Network-as-a-Service models. L2VPNs also automate more easily across multiple service provider segments. LISP is mentioned as a potential alternative to MPLS for private WANs built on top of L2VPN services. ## Full article daily.dev links to this article rather than hosting it. Read it at the original source: ## Questions this post answers ### Why do customers prefer layer-2 VPNs over layer-3 VPNs? L2VPNs are preferred primarily because of provisioning simplicity. L3VPNs typically require weeks of configuration negotiation with a service provider and are difficult to automate. L2VPNs need only a few parameters to connect, support Network-as-a-Service models, and can be automatically provisioned across multiple service provider segments. The trade-off is that customers must install their own edge routers to separate their network from the provider's. _Network engineers weighing WAN connectivity options find the trade-offs discussed on daily.dev._ --- Tags: [#vpn](https://daily.dev/tags/vpn) [View this post on daily.dev](https://daily.dev/posts/repost-why-are-layer-2-vpns-so-popular-ipspace-net-blog-gt2a9qecz) ```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":"Repost: Why Are Layer-2 VPNs So Popular? « ipSpace.net blog","url":"https://daily.dev/posts/repost-why-are-layer-2-vpns-so-popular-ipspace-net-blog-gt2a9qecz","mainEntityOfPage":{"@type":"WebPage","@id":"https://daily.dev/posts/repost-why-are-layer-2-vpns-so-popular-ipspace-net-blog-gt2a9qecz"},"datePublished":"2026-08-11T08:51:56.741Z","dateModified":"2026-08-11T08:53:36.931Z","description":"A reposted comment from Béla Várkonyi explains why Layer-2 VPNs are gaining popularity over Layer-3 VPNs, primarily due to provisioning complexity.
