Henning:

Excellent resources! Thanks.

Sahana:

If you have the topology like this, you can use the following 
instructions to make the clients to ping each other. (Just ensure that 
you don't have any iptables rules which interfere the traffic)

    192.168.1.0/24                      192.168.2.0/24
C1 <------------> R1 <---> R2 <---> R3 <------------>C2
    .2          .1                      .1          .2

* On C1, add default route by executing the following command

     ip route add default via 192.168.1.1

* On C2, add default route by executing the following command

     ip route add default via 192.168.2.1

* On R1, add the HNA entry for 192.168.1.0/24 network and restart the 
OLSR daemon. eg.,

Hna4 {
     192.168.1.0      255.255.255.0
}

* On R2, add the HNA entry for 192.168.2.0/24 network and restart the 
OLSR daemon. eg.,

Hna4 {
     192.168.2.0      255.255.255.0
}

If everything goes fine, you can see routes to 192.168.1.0/24, 
192.168.2.0/24 on all the routers (R1, R2, R3) using 'ip route' command. 
Also, the clients (C1, C2) should be able to ping each other.
