I just tripped over following effect:
Given a notebook with ath0 & fxp0.
ath0 being the internet access path
fxp0 providing NATed internet service via
When running routed on this machine (not
really necessary in that setup) routed
detects a SICK/BROKEN interface (ath0) because
the ierrs reported exceed input pakets.
So routed drops the routes to that interface
(including cloning llinfo thus disabling ARP) and
the internet link is gone.
- the high ierr counts on ath0 - do they make sense
wrt/ routed's interpretation of a 'broken' interface.
- is it ok that routed cuts off the last somewhat working
link to the rest if the world ?
I guess it all depends on the semantics of the counters which are
said to have ill/no defined meanings somewhere in the manial/code base.
If these semantcs are not well defined how can we allow routed to make
decisions based on the counters ?
What needs to be fixed?
- routed - ignore errors - maybe configurable
- ath(4) - tune down on ierrs
I also wonder whether routed really should disable the 'last' link.
