Following a community-reported GitHub issue, netlab was updated with configuration tweaks and integration tests to enable MPLS on cEOS containers. MPLS support for cEOS is available in netlab release 1.9.0 (currently at 1.9.0-dev2), with plans to create MPLS labs running in GitHub Codespaces soon. ## Full article daily.dev links to this article rather than hosting it. Read it at the original source: ## Questions this post answers ### Does Arista cEOS support MPLS data plane in containers? Arista cEOS gained a working MPLS data plane starting with release 4.31.2F. Previously, cEOS containers lacked MPLS data plane support even though EOS had MPLS configuration templates. With netlab release 1.9.0 (available as 1.9.0-dev2), MPLS can be configured and used on cEOS containers, confirmed through a batch of integration tests. _Network engineers running containerized Arista labs track capability updates like this on daily.dev._ ## Similar posts on daily.dev - [MPLS/VPN with SR-MPLS Core « ipSpace.net blog](https://daily.dev/posts/mpls-vpn-with-sr-mpls-core-ipspace-net-blog-nw3uwiphe) · ipSpace.net Blog · 0 upvotes · 0 comments - [EVPN with SR-MPLS Core « ipSpace.net blog](https://daily.dev/posts/evpn-with-sr-mpls-core-ipspace-net-blog-taobtibzc) · ipSpace.net Blog · 0 upvotes · 0 comments - [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 - [Arista cEOS Does Not Apply ACLs to Control-Plane Traffic « ipSpace.net blog](https://daily.dev/posts/arista-ceos-does-not-apply-acls-to-control-plane-traffic-ipspace-net-blog-ieh2uzhm7) · ipSpace.net Blog · 0 upvotes · 0 comments - [Multivendor SR-MPLS « ipSpace.net blog](https://daily.dev/posts/multivendor-sr-mpls-ipspace-net-blog-qekokwduk) · ipSpace.net Blog · 0 upvotes · 0 comments --- Tags: [#networking](https://daily.dev/tags/networking) [View this post on daily.dev](https://daily.dev/posts/arista-ceos-got-working-mpls-data-plane-ipspace-net-blog-dxutyqdkg) ```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":"Arista cEOS Got Working MPLS Data Plane « ipSpace.net blog","url":"https://daily.dev/posts/arista-ceos-got-working-mpls-data-plane-ipspace-net-blog-dxutyqdkg","mainEntityOfPage":{"@type":"WebPage","@id":"https://daily.dev/posts/arista-ceos-got-working-mpls-data-plane-ipspace-net-blog-dxutyqdkg"},"datePublished":"2026-08-11T08:52:03.755Z","dateModified":"2026-08-24T07:03:50.570Z","description":"Arista cEOS containers now support a working MPLS data plane starting with release 4.31.2F.
