I currently peer (via tunnels through my IPv4 connection) with securebit (aka tunnelbroker.ch), freetransit.ch and route48.org (but the list varies a bit over time),
The original motivation was my frustration about my ISP not offering native IPv6 and general interest in internet routing.
Sorry, I missed your message. I'm using bird2 (and networkd for the tunnels) but sending the configs here doesn't work that great. Feel free to reach out by mail and I can send you a copy (news@2krueger.de).
