The two that I'd like to use are IPv4 with IPv6 next-hop (RFC 9229), mainly to keep my network as IPv6 single stack as possible, with just IPv4 mainly on loopbacks, and delay based metrics (draft-jonglez-babel-rtt-extension-02), as in my case some Internet routing quirks mean that least-hops isn't always the lowest latency path between my hosts. Neither are critical, and bird is doing a wonderful job, so it isn't a big issue if I just keep forgoing these. >> Any clues what sort of limit I may have reached or how to mitigate >> this?

That helps me understand what is going on a lot better.
