Hi,
olsrd2 only sets routes in the routing table... it doesn't touch traffic at
all. So if you can exchange data between the two PIs (which would also work
without the routing agent because of your subnet mask), everything else
should not depend on olsrd2.
You have checked if a ping works between both sides?
