Andreas, Thomas et al.,

yesterday evening I have some smalltalk with elektra about olsrd settings 
for more routing stabiltity. Because there are several devices currently 
running that Freifunk Firmware, I want to socialize about changed default 
settings prior to a mass deploy with the next FFF update. Currently, we use 
these defaults (a bit slower than the settings proposed with the source 
package to save CPU power with a more static not moving nodes setup):

Pollrate                0.5
TcRedundancy            2
MprCoverage             3
LinkQualityWinSize      18
LinkQualityLevel 2
UseHysteresis no
Interface "ethX"
        HelloInterval           5.0
        HelloValidityTime       90.0
        TcInterval              15.0
        TcValidityTime          90.0
        MidInterval             15.0
        MidValidityTime         90.0
        HnaInterval             15.0
        HnaValidityTime         90.0

Elektra points out, that it would be more stable with olsrd-0.4.10 if 
TcInterval is shorter than the HelloInterval. This may overcome the "routing 
loop problem" encountered occasionally because topology info is spreaded 
more frequently. My suggestion: Hello=10, TC=5, Validity stays 90. Also: a 
change of LinkQualityWinSize to 100. This makes HelloInterval * 
LinkQualityWinSize < HelloValidityTime). OK? Caveats? Any Comments?

TIA Sven-Ola
