[Bug 1807569] Re: netplan accept-ra disables slaac

[Ryan Harper]

Thanks for filing the bug.

Can you provide the netplan you used?

Also, if possible, could you run:

mkdir /etc/systemd/system/systemd-networkd.service.d/
echo -e "[Service]\nEnvironment=SYSTEMD_LOG_LEVEL=debug" > /etc/systemd/system/systemd-networkd.service.d/10-debug.conf 


Reboot and then provide the output from the journal like so?

journalctl -b 0 -o short-monotonic -u systemd-networkd.service

And tar up whatever is in /run/systemd/network/* ?


Lastly, if you do not specify accept_ra at all, does this affect the results?

Thanks!

Title:
  netplan accept-ra disables slaac

Status in netplan:
  Incomplete
Status in netplan.io package in Ubuntu:
  Incomplete

Bug description:
  Hello,

  The netplan flag configuration "accept-ra" does not only enable or
  disable the use of router advertisements, but also stateless
  configuration of addresses. This makes it impossible to configure a
  host with only a static IPv6 address, but with a gateway received
  through RA's (equivalent to sysctl autoconf=0 and accept_ra=1).
