Note that the slowness here is due to babel-pinger (which is really just
a hack) rather than to Babel itself.  In the absence of packet loss,
Babel itself will update the route in 100ms per hop.

Please log into a node that you feel has selected the wrong route, and
do

  kill -USR1 $(cat /var/run/babel.pid)

This will dump Babel's internal tables into the log file; please send
the result to this list.  (Not the whole log, just the dump starting
with ``My id ... seqno ...''.)

Check the ``-k'' option to babeld (lower values are higher priorities).

Babel will recover automatically when it eventually notices the
discrepancy (which might very well not happen until you shutdown Babel).
