New blog post: Running your own Autonomous System on FreeBSD.
Got an AS number and IPv6 /48 via RIPE, set up a FreeBSD BGP router with FRR, two upstreams, and built GRE/GIF tunnels ti bring my own globally routable addresses to servers at different providers.
The interesting part: dual-FIB policy routing lets FreeBSD jails speak from both provider and BGP addresses simultaneously.
