Hello,
the first message says that `10.0.0.1` is either your own address or it
isn't considered reachable from what we can see on the interfaces.
To find out what causes the `File exists` message, we'll need you to
allow `debug all;` inside the `ipv4` block of your `protocol kernel`
and send us a log snippet around this message when it appears next time.
Otherwise, we know nothing. It is possibly BIRD trying to export a
colliding route.
Maybe, but that's a wild guess, you're running OpenBSD (?) and you have
another route inside BIRD for xx.yy.zz.0/24. If that's right, there is
quite a lot additional questions about what you are trying to achieve
and whether this is a good or bad state. But I'll keep them for later.
Have a nice day!
Maria
