You're not mistaken about the interpretation of those fields, but... While NM was running, is it possible there was a previous RA that had "stateful other conf" (eg the M/managed flag) set? To avoid ping-pong with RA changes or multiple router advertisements from different routers NM will cache the "most managed" level. Dan > Which I presume is what leads to: > > 1138 ?
