How are you measuring?  Are you rebooting your routers, or merely toggling
links up/down?

If the latter, than there is a problem.  If the former, then you should
either make sure that the state file is preserved across reboots, or run
with "random-id true".

Explanation: a Babel router's seqno must be preserved across reboots in
order to avoid spuriously triggering the loop-avoidance algorithm.  This
is what the state file is used for.  If for some reason you cannot
preserve the seqno, the "random-id" option can be used to create a new set
of loop-avoidance state at each boot.
