#BGP is classified as a #PathVector routing protocol, and it makes #RoutingDecisions based on paths, network policies, or #RuleSets configured by a network administrator.

Wrote up a little blog post about my tool called "Lagbuster" that I use to switch between upstream providers based on the health of the path.

Building Lagbuster: automated BGP path switching for the rest of us

BGP is great at keeping you connected, but it doesn't care if your traffic is taking the scenic route up and down the East Coast.

New post: Part 4 of running my own AS.

A direct BGP session with Hetzner on FogIXP, a fourth FreeBSD edge in Zürich, and a MikroTik at home speaking iBGP into the /48 - so my home LAN now has provider-independent IPv6 and exits AS201379 like any other site.

Plus a two-condition route-map that steers DTAG-bound traffic over Vultr.

I've submitted a Pull Request to update MacPorts' rpki-client to 9.8 here:

https://github.com/macports/macports-ports/pull/32251

GitHub Continuous Integration checks passed OK!

It's up to someone else to merge it.

I couldn't help but notice the most recent OpenBGPD release announcement mentioned something about a -portable branch? Admittedly, it has been a very long time since I looked at building OpenBGPD on macOS, but maybe it is worth looking at again? I still think it is probably ill advised to use macOS for something as critical as routing insomuch as it sleeps, with abandon, unless /usr/bin/caffeinate is invoked.

In my latest post for @kentikinc , I introduce the concept of ephemeral leaks, short-lived routing anomalies that appear briefly during #BGP convergence and fill the output of public leak detection tools like @cloudflareradar and its predecessors.

https://www.kentik.com/blog/ephemeral-leaks-and-automated-bgp-route-leak-detection/

Ephemeral Leaks and Automated BGP Route Leak Detection

Many BGP route leaks reported by automated detection systems are actually brief, low-impact artifacts of normal BGP convergence. Doug Madory examines examples from Cloudflare Radar, Routeviews, and Jared Mauch’s long-running leak detector to show how these “ephemeral leaks” arise, why they usually don’t disrupt traffic, and why they still matter for routing security.
