IPv6 on AWS fails after 30 seconds

Jordan Geoghegan-2
Hi Folks,

I was able to get OpenBSD working on AWS thanks to an awesome script by
ajacoutot@ : https://github.com/ajacoutot/aws-openbsd

Everything seems to be working great, except I've had difficulty getting
IPv6 working properly.

AWS unfortunately uses DHCPv6 rather than slaac for IPv6 address
assignment, thus putting 'inet6 autoconf' in my /etc/hostname.xnf0 file
wasn't enough. I installed dhcpcd from ports, and was able to pull an
address no problem. Weirdly, I'm able to ping6 addresses, but only for
roughly 10 seconds after booting, after that, the connection seems to
die. It seems that I am able to get 8 pings out to google before the
IPv6 connection drops.

ip-172-31-6-xxx$ ping6 google.ca
PING google.ca (2607:f8b0:4020:804::2003): 56 data bytes

20 packets transmitted, 8 packets received, 60.0% packet loss
round-trip min/avg/max/std-dev = 1.349/1.370/1.385/0.012 ms

When I try it again:

ip-172-31-6-xxx$ ping6 google.ca
PING google.ca (2607:f8b0:4020:804::2003): 56 data bytes
^C

8 packets transmitted, 0 packets received, 100.0% packet loss

I don't have a huge amount of experience with IPv6 as my local ISP
doesn't support it, but I was able to get a Linux image working with
IPv6 no problem. I have the Linux VM in the same subnet as the OpenBSD
image, and they are able to ping6 and ssh -6 each other all day without
issue, which makes me think there is some sort of routing issue going on.

Any insight or advice would be much appreciated.

I just realized I forgot to include my dhcpcd log info. Please see below.

Any insight or advice would be much appreciated.
