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
