Hi,
I got once that problem and added the default-route statically as a
hotfix (I used a setup with FHRP, getting the route via RA was not a
strong-requirement so I did not tshoot further)
Did you try to set the `accept_ra=2` under the interface itself instead
of all ?
reading the doc:
```
Functional default:
enabled if local forwarding is disabled.
disabled if local forwarding is enabled.
```
I'm wild guessing assuming that `all.accept_ra=2` might be overided by a
default `disabled` under the interface.
Best regards,
Nicolas

Hello everyone,
I'm trying to configure my machine as an IPv6 router. When I set
net.ipv6.conf.all.forwarding=1, the default routes get deleted, which
is expected. But setting net.ipv6.conf.all.accept_ra=2 does not help
either. Set it before or after net.ipv6.conf.all.forwarding=1, the
default routes WILL get deleted and I've to add it manually. I've even
tried setting these in sysctl.conf and rebooted with the same effect.

Yes. I can confirm. Interface specific accept_ra works as expected.
Thanks!
