[Olsr-users] 3 PCs setup for OLSR

[(spam-protected)]

Hi Markus,
   thanks Markus.....:)
   You were right as I was getting some other outputs in #ip rule
command as I was having some force entries for routing table select.
   I changed the olsrd/conf file and commented the RtTable entries to
select kernel default table by olsrd.
   Now in setup PC1<-------->(eth0)PC2(eth1)<----------->PC3, We are
able to ping PC1 frpm PC3 and vice-versa.
   Now I have to run a vedio streaming from PC1 to PC3. Do you have any
idea to do it?
Vijai

this means that pc3 searches for its (possible wrong) Default gateway
which it only does if there no olsr routes which mach better than the
default route

looks correct, but as it doens`t work,...

check (for exampl eon pc3) what
#ip route
(should contain routes to the other olsr routers) and #ip rule (should
be only 3 lines) print out


and pls leave the bmf plugin away (at least for the moment)


if ip route doen`s print the expected routes configure httpinfo (or
txtinfo), and check there if the links get symmetric, and if the olsr
wants to create routes (i mean if it list routes there)
