[olsr-dev] Policy Routing Hack

[Sven-Ola Tuecke]

Hi Bernd,

for me it's working fine. However, the struct tcmsg change is appreciated of 
course. What's wrong on your side? Does-not-compile or has-no-effect? In the 
latter case, you need to add some policy stuff first. Example: set 
rttable=123 in olsrd.conf and hack in something in the start script, e.g. 
"ip rule add from 10.0.0.0/8 table 123" and maybe "ip rule add from 
192.168.0.0/16 to 10.0.0.0/8 table 123" provided that your mesh runs on 
10.x.x.x. After starting olsrd, the "route -n" command does not show any 
OLSR route. You need to enter "ip route ls table 123" for this. And you need 
the ip command, "apt-get install iproute" or so...
