Or maybe we have a bug. So here is a default gateway. So far as I know it is getting a /56 actually, not a /60, but it is requesting a /60 and thus distributing a source specific route to that /60. default from :: via fe80::201:5cff:ee62:b646 dev ge00 proto static metric= 1024 # should I even have a default route at all? default from 2001:558:6045:e9:44a9:4a25:ece9:55c3 via fe80::201:5cff:ee62:b646 dev ge00 proto static metric 1024 # my uplink, looks sane default from 2601:c:ce00:9d0::/60 via fe80::201:5cff:ee62:b646 dev ge00 proto static metric 1024 # and see that /60... # and then there is the default ipv6 address assignements on cero. 2601:c:ce00:9d1::/64 dev gw10 proto kernel metric 256 expires 326362sec Now, where my brain crashes: shouldn't 2601:c:ce00:9d1::/64 actually be something like 2601:c:ce00:9d01::/64 not, 2601:c:ce00:9d1::/64? (see the 01?)? OK, so, like, I have another babel source specifc gateway a few hops in from there, I add ip -6 addr add 2601:c:ce00:9d01::1/64 dev wlan0-1 that doesnt work. I make it be ip -6 addr add 2601:c:ce00:9d6::1/64 dev wlan0-1 and that does. --=20 Dave T=C3=A4ht http://www.bufferbloat.net/projects/bloat/wiki/Upcoming_Talks
