Hi Toke, Looks like I never responded to this :O.

The CPU usage is pretty much what you'd expect babel and bird are the top offenders but dnsmasq is also spinning quite heavily. During the original tests I was monitoring CPU usage with htop to make sure I'm not measuring idle route insertion activity FYI. I just tried to reproduce the problem to make sure dnsmasq isn't interfering also, but I can't seem to reproduce it now. Perhaps this was actully a kernel bug that since got fixed by a kernel upgrade. This is on a Debian 11 (bullseye) system, according to my dpkg.log I likely had 5.10.0-11-amd64/5.10.92-1 at the time of the original tests whereas I have 5.10.0-12-amd64/5.10.103-1 now. I tried with the old version too but I can't seem to get the problem to trigger anymore now.
