[Olsr-users] OLSR routing table plugin

[Henning Rogge]

Hi,

if you want to use a custom metric, you have to write a custom metric 
implementation (one example of this is in src/lq_plugin_default_ff.c).

If you just want to put the result of the dijkstra into a different 
routing table, you can use a configuration parameter. Look for the 
parameters "RtTable", "RtTableDefault" and "RtTableTunnel" in the 
documented configuration file in files/olsrd.conf.default.full

The Olsr.org implementation only accepts link costs as a 32 bit unsigned 
integer between 1 and 2^24-1. It would require an invasive modification 
of the core to change this.

Consider multiplying your metric with a constant value to transform a 
fractional number to an integer.
