Since SR/MPLS shares the same data plane as traditional MPLS — differing only in label allocation (network-wide Segment Identifiers vs. locally-significant labels, and routing protocol integration vs. LDP) — the security recommendations are essentially the same. Key guidance includes: preventing routing protocol adjacencies on customer-facing interfaces, using encryption below the MPLS encapsulation layer, enabling routing protocol authentication to guard against rogue devices on transport links, and applying standard device hardening on PE and P routers. RFC 5920 (Security Framework for MPLS and GMPLS Networks) is cited as the authoritative reference. ## Full article daily.dev links to this article rather than hosting it. Read it at the original source: ## Questions this post answers ### What are the main security differences between traditional MPLS and SR/MPLS that I need to account for in my backbone design? There are no meaningful security differences between traditional MPLS and SR/MPLS at the data plane level. The only architectural difference is label allocation: SR/MPLS uses network-wide Segment Identifiers distributed via routing protocols instead of locally-significant LDP labels. Security recommendations are identical: block routing adjacencies on customer-facing interfaces, use encryption below MPLS encapsulation, enable routing protocol authentication, and harden PE and P devices. _Engineers designing SR/MPLS backbones track evolving network security guidance on daily.dev._ ### What RFC covers the security framework for MPLS and GMPLS networks? RFC 5920, titled 'Security Framework for MPLS and GMPLS Networks', is the authoritative reference for MPLS backbone security. It covers the threat model and security recommendations applicable to both traditional MPLS and SR/MPLS deployments, since the core data plane and security surface are essentially the same across both technologies. _Keeping up with MPLS and network security standards is easier when relevant posts surface in one place — daily.dev covers that ground._ ## 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 - [Multivendor SR-MPLS « ipSpace.net blog](https://daily.dev/posts/multivendor-sr-mpls-ipspace-net-blog-qekokwduk) · 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 --- Tags: [#security](https://daily.dev/tags/security) [View this post on daily.dev](https://daily.dev/posts/mpls-security-framework-ipspace-net-blog-oodxusr89) ```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":"MPLS Security Framework « ipSpace.net blog","url":"https://daily.dev/posts/mpls-security-framework-ipspace-net-blog-oodxusr89","mainEntityOfPage":{"@type":"WebPage","@id":"https://daily.dev/posts/mpls-security-framework-ipspace-net-blog-oodxusr89"},"datePublished":"2026-08-11T08:52:46.119Z","dateModified":"2026-08-11T09:03:58.136Z","description":"A practical overview of security considerations for building a greenfield SR/MPLS backbone.
