With thousands of concurrent aircraft, multiple radio links going up and down, and up to 16 subnets per aircraft with different routing policies, LISP's simpler architecture and faster mobility event handling outperform BGP's complex path selection. He also highlights LISP's support for anchorless, fully distributed mobility without a single point of failure — something PMIPv6 and BGP cannot match at scale. Cisco's internal benchmarks reportedly confirmed LISP's speed advantage, and Boeing Connexion's failure with BGP-based mobility is cited as a real-world cautionary example. Some gaps remain: reliable transport standardization, subnetwork mobility support in MS/MR, and LCAF extensions are still needed. ## Full article daily.dev links to this article rather than hosting it. Read it at the original source: ## Questions this post answers ### Why is LISP considered better than BGP for network mobility in aviation or vehicle scenarios? LISP with PUBSUB handles mobility events faster and more simply than BGP because BGP's complex path selection algorithm is not designed for mobility. On the same CPU, LISP processes mobility events significantly faster — a Cisco internal benchmark confirmed LISP beat BGP experts' best configurations. BGP also lacks standardized support for parallel active multilink mobility with Priority and Weight, while LISP provides fully distributed, anchorless mobility without a single point of failure. _Network engineers evaluating routing protocols for mobile or safety-critical deployments track discussions 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: [#bgp](https://daily.dev/tags/bgp), [#evpn](https://daily.dev/tags/evpn), [#lisp](https://daily.dev/tags/lisp), [#networking](https://daily.dev/tags/networking) [View this post on daily.dev](https://daily.dev/posts/repost-the-real-lisp-mobility-use-case-ipspace-net-blog-3lfms0zs7) ```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: The Real LISP Mobility Use Case « ipSpace.net blog","url":"https://daily.dev/posts/repost-the-real-lisp-mobility-use-case-ipspace-net-blog-3lfms0zs7","mainEntityOfPage":{"@type":"WebPage","@id":"https://daily.dev/posts/repost-the-real-lisp-mobility-use-case-ipspace-net-blog-3lfms0zs7"},"datePublished":"2026-08-11T08:54:44.459Z","dateModified":"2026-10-15T02:24:17.053Z","description":"Béla Várkonyi argues that LISP (with PUBSUB) is significantly better suited than BGP for high-scale mobility scenarios such as ground-to-airplane networks....","image":"https://media.daily.dev/image/upload/s--qPvKM23u--/f_auto/v1722860399/public/Placeholder%2009","thumbnailUrl":"https://media.daily.dev/image/upload/s--qPvKM23u--/f_auto/v1722860399/public/Placeholder%2009","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/repost-the-real-lisp-mobility-use-case-ipspace-net-blog-3lfms0zs7","interactionStatistic":[{"@type":"InteractionCounter","interactionType":{"@type":"LikeAction"},"userInteractionCount":0},{"@type":"InteractionCounter","interactionType":{"@type":"CommentAction"},"userInteractionCount":0}],"keywords":"bgp,evpn,lisp,networking","timeRequired":"PT3M"} {"@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":"Repost: The Real LISP Mobility Use Case « ipSpace.net blog"}]} {"@context":"https://schema.org","@type":"FAQPage","@id":"https://daily.dev/posts/repost-the-real-lisp-mobility-use-case-ipspace-net-blog-3lfms0zs7#faq","mainEntity":[{"@type":"Question","name":"Why is LISP considered better than BGP for network mobility in aviation or vehicle scenarios?","acceptedAnswer":{"@type":"Answer","text":"LISP with PUBSUB handles mobility events faster and more simply than BGP because BGP's complex path selection algorithm is not designed for mobility.
