10 sec to create a new route in a very simple topology? I hope that it isn't

There are only 3 Nodes (A, B and C). First there is a direct link from A to
A ----- C and everythinks goes right.
After 5 seconds I change the topology (with iptables) to:
A --------- B -------- C so that there is no direct link between
A and C.
After 5 seconds the topology will change back. But the 5 sec are not enougth
that OLSR can create a new route. So I wait for 10 to 15 sec until the new
is created. So I change in the config file the hello_interval and the
nothing realy happens.
