Yes... you could easily ping the neighbor even without running OLSRd at all, 
because its in ARP range. OLSRd cannot prevent this.

Keep in mind OLSRd does only setup IP forwarding routes, it does not forward 
the traffic itself.

You might be able to do this by setting up a blackhole route for the mesh 
network, so that all unicast packets without an explicit OLSRd routes are not 
send at all.

But this neither would prevent an 'attacker' from sending the packet anyways 
nor would it block multicast traffic from services like Zeroconf.
