https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D253469 --- Comment #9 from Alexander V. Chernikov <melifaro@FreeBSD.org> --- Good. So from ICMP6 input histogram, it can be seen we received these RA messages. Do you see multiple messages "nd6_options: unsupported option 24 - option ignored "? As far as I understand, RA messages are received by the nd6_ra_input(), processed halfway there (as nd6_options() is called and likely does not fai= l). The next part it can fail is enabled forwarding (net.inet6.ip6.forwarding). Do you have it turned off (or have net.inet6.ip6.rfc6204w3 turned on)? If forwarding is turned off, do you mind sharing "ndp -i re0" and showing input RA message? e.g. "tcpdump -i re0 -lnpvvs0 icmp6" --=20 You are receiving this mail because: You are the assignee for the bug.=
