[Babel-users] switching cerowrt to quagga-babeld issues

Please note that the auth TLV format is changing right as we speak
(commit f0f71a), so if you enable auth by default, warn your users about
the incompatibilities.

I think somebody mentioned that already.

Please don't use the rxcost parameter, which is specific to the ETX
algorithm, use filtering instead:

  in if wlan42 metric 32

In Quagga, this should be done using route-maps.  Except that we haven't
implemented route-maps yet.

Yep, route-maps are not implemented for Babel yet.

You should be able to do that with an access-list.  Access-lists are
only half-implemented in Babel right now, but the current support should
be sufficient for the above.
