[OLSR-users] OLSR over managed links

[Sven-Ola Tuecke]

Hello,

in Berlin we are using olsrd over managed links also. OLSR broadcasts are 
exchanged between the Master and the Clients and routes are calculated the 
usual way. Seems to be Ok. Heres an example:

eth0: 104.0.0.13/30 (ether)
wlan0: 104.0.0.13/8 (ad-hoc)
wlan1: 104.0.2.1/24 (master)

(The different netmasks, 255.0.0.0 for ad-hoc, 255.255.255.0 for managed and 
255.255.255.252 for ether p2p link are chosen to make it possible to contact 
the devices even if no olsr-host-routes while all network cards are working 
in the same network segment 104.0.0.0/8. This works under Linux, because the 
routing table algo priorize a narrower netmask).

If two clients (104.0.2.111 and 104.0.2.222 in the above sample context) are 
sending OLSR broadcasts, the broadcasts are repeated by the Master 
104.0.2.1 - right?. So olsrd may think "hey - theres a possible direct 
connection between 104.0.2.111 and 104.0.2.222". In most cases this is not 
the case. Question: Any suggestion for olsrd-route cleanup here? And: do 
client mode wlan stations communicate with each other? Or is it better to 
make an iptables rule on all client mode wlan cards here, e.g. "do receive 
OLSR from 104.0.2.1 but do not receive OLSR from other 104.0.2.0/8".

TIA, Sven-Ola
