Of course, my link is sometimes congested, but i don't know the current 
max. bandwidth, because the link-quality is jumping, so the bandwidth is 
between 5 and 15 MBit. The most of the time, stable at 15 MBit.

ROUTE A have stable bandwidth at 60MBit, so i like to use ROUTE B only 
for backup. But currently ROUTE B is the primary choose from olsr.

Now i will give LinkQualityMult a try.

How can i reload olsrd.conf without killing and restarting olsr?
Currently i always have about 10-30 sec. of downtime.

To solve/minimize my "flapping" problem, i've installed a tc-rule a long 
time before, because the link was allways degraded on a high usage:
