“Some time” here being, with an interval setting of 5s(!), a mere 64 seconds (after sending 7 RAs).
Oh, wait, there’s been an 8th one, 530 s after #7.
I’m not capturing solicitations though right now, so I’m not sure whether a machine asked for it.
I mean, the source (https://thekelleys.org.uk/gitweb/?p=dnsmasq.git;a=blob;f=src/radv.c;h=3255904b90ec3a53561311fe305f39e6d5c3bce3;hb=9f20afb1a8c1e46dcc6658d28148a3b785a53792) says something about “some ra_times will end up zeroed if it's not appropriate to advertise those contexts” but I struggle to understand what the exact conditions of that might be and why my setup could be “inappropriate”.
This is the personal Mastodon instance of Tim Weber (also known as scy). Because federation.
