Not if you set the accept_ra_rt_info_max_plen sysctl to >= 48 (and the router implements RFC 7084 L-3). As far as I know, this sysctl is 0 by default which causes the kernel to ignore RIOs. I believe that Windows do accept RIOs by default so that's probably why it worked for Brian. NetworkManager user-space RA processing will also respect RIOs by default. Tore
