The `bgp route-reflector preserve-attributes` command does not fix this for EVPN. The workaround is removing `next-hop-self` globally and using a route map that sets the next hop only for EBGP-learned routes. A follow-up note confirms that Arista EOS 4.29.0F added per-address-family `next-hop-self` support for IPv4 and IPv6 unicast, partially resolving the issue. ## Full article daily.dev links to this article rather than hosting it. Read it at the original source: ## Questions this post answers ### Why is my Arista EOS BGP route reflector not sending EVPN routes between leaf switches when next-hop-self is configured? When `neighbor next-hop-self` is configured globally in Arista EOS, it also applies to the EVPN address family, changing the next hop to the spine/route-reflector. Because the spine lacks VXLAN interfaces to handle that traffic, it suppresses the reflected EVPN updates entirely. The `bgp route-reflector preserve-attributes` command does not override this for EVPN. Removing `next-hop-self` globally restores EVPN route reflection. _Engineers debugging EVPN fabric issues on Arista track fixes like the 4.29.0F per-AF next-hop-self support on daily.dev._ ### How do I fix next-hop-self breaking EVPN on an Arista EOS route reflector while still changing next hops for IBGP+EBGP IPv4 routes? Use a route map instead of the global `next-hop-self` command. Configure a route map that matches external (EBGP) routes and sets the next hop to the peer address, with a second permit entry to pass all other routes unchanged. Apply this route map as an outbound policy on IBGP neighbors in the IPv4 address family. This avoids the global next-hop-self affecting EVPN. _Networking engineers solving Arista BGP edge cases share workarounds like this on daily.dev._ ### Does Arista EOS support per-address-family next-hop-self configuration for BGP? Yes, starting with EOS release 4.29.0F, `neighbor next-hop-self` can be configured within IPv4 and IPv6 unicast address families. Prior to this release, next-hop-self was only configurable at the global BGP neighbor level, causing it to unintentionally affect EVPN address family processing on route reflectors. _Arista EOS release notes and their impact on BGP fabric designs surface regularly for networking engineers on daily.dev._ ## Similar posts on daily.dev - [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 - [The Never-Ending IPv6 Loopback Prefix Saga « ipSpace.net blog](https://daily.dev/posts/the-never-ending-ipv6-loopback-prefix-saga-ipspace-net-blog-4nlhgh10l) · ipSpace.net Blog · 0 upvotes · 0 comments --- Tags: [#bgp](https://daily.dev/tags/bgp), [#evpn](https://daily.dev/tags/evpn) [View this post on daily.dev](https://daily.dev/posts/more-arista-eos-bgp-route-reflector-woes-ipspace-net-blog-uaebo69fr) ```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":"More Arista EOS BGP Route Reflector Woes « ipSpace.net blog","url":"https://daily.dev/posts/more-arista-eos-bgp-route-reflector-woes-ipspace-net-blog-uaebo69fr","mainEntityOfPage":{"@type":"WebPage","@id":"https://daily.dev/posts/more-arista-eos-bgp-route-reflector-woes-ipspace-net-blog-uaebo69fr"},"datePublished":"2026-08-11T08:52:36.609Z","dateModified":"2026-10-14T02:35:50.865Z","description":"Arista EOS has a quirk where the global `neighbor next-hop-self` command affects EVPN address family processing, causing route reflectors to silently drop EVPN...","image":"https://media.daily.dev/image/upload/s--P4t4XyoV--/f_auto/v1722860399/public/Placeholder%2001","thumbnailUrl":"https://media.daily.dev/image/upload/s--P4t4XyoV--/f_auto/v1722860399/public/Placeholder%2001","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/more-arista-eos-bgp-route-reflector-woes-ipspace-net-blog-uaebo69fr","interactionStatistic":[{"@type":"InteractionCounter","interactionType":{"@type":"LikeAction"},"userInteractionCount":0},{"@type":"InteractionCounter","interactionType":{"@type":"CommentAction"},"userInteractionCount":0}],"keywords":"bgp,evpn","timeRequired":"PT4M"} {"@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":"More Arista EOS BGP Route Reflector Woes « ipSpace.net blog"}]} {"@context":"https://schema.org","@type":"FAQPage","@id":"https://daily.dev/posts/more-arista-eos-bgp-route-reflector-woes-ipspace-net-blog-uaebo69fr#faq","mainEntity":[{"@type":"Question","name":"Why is my Arista EOS BGP route reflector not sending EVPN routes between leaf switches when next-hop-self is configured?","acceptedAnswer":{"@type":"Answer","text":"When `neighbor next-hop-self` is configured globally in Arista EOS, it also applies to the EVPN address family, changing the next hop to the spine/route-reflector.
