Looking at it, it looks to come around the completion of DAD for my re0 link local and autoconf IPv6 address. Sorry if some of my terminology is poor, my IPv6 knowledge has got= ten rusty. inet.inet6.ip6.forwarding =3D 0 inet.inet6.ip6.rfc.6204w3 =3D 0 The output of ndp -i rs0: linkmtu=3D1500, maxmtu=3D1500, curhlim=3D64, basereachable=3D30s0ms, reacha= ble=3D18s, retrans=3D1s0ms Flags: nud accept_rtadv auto_linklocal For the tcpdump, I see nothing showing up. I have tried with my firewall bo= th on and off. With promisc mode enabled I am getting router solicitation pack= ets. Actually, what's also interesting is when I enable promiscuous mode the RAs work and I don't lose my routes. Then if I turn promiscuous mode off I lose= my route again. I see there are nd6 updates available in releng/13.0 branch. So I'm going to create a new boot environment and see if I have these issues a= fter the update. I'll be keeping my existing boot environment with the issues. I= 'm getting src updates via gitup. For the future: # Have: c48cbd0254dedd363ab569692ddf3395b6214412 # Want: 1e76911d62ed4b66bc21cfc22101ef6b20cd6630 I'll update this bug report after things compile and such. --=20 You are receiving this mail because: You are the assignee for the bug.=
