[Olsr-users] question about HNA function

[(spam-protected)]

Dear all
    I am a newbie for olsrd,I would like to ask some questions about  
HNA function in olsrd. Currently,I try to implement the wireless mesh  
network which consist of two sub networks. The wireless router has two  
interfaces. One is used for communicating with other wireless router  
by using olsrd application called mesh sub network. Another interface  
is configured as AP mode to provide the connectivity to client  
(laptop,PDA,etc.).The Client nodes are independent to move to all  
wireless router and still keeping the same IPv6 address. In my  
objective, I would like to use the HNA message to broadcast the  
current location of clients in each wireless router in order to make a  
route to the clients. The wireless routers have to detect the client's  
address and put these address to HNA message dynamically. My question  
is, how can I put the client's address to HNA message. I found some  
documents stated that IP address will be kept in a local HNA table and  
this set is implemented in src/local_hna_set.c. However, now I used  
olsrd version 0.5.6 r5 and I cannot find the local_hna_set.c in this  
version. Thank you very much for paying attention to my question.

Thank you very much
