[OLSR-users] Re: olsr-users Digest, Vol 10, Issue 20

[(spam-protected)]

Hi,

Thanks for the reply. 

Actually I'd tried to use HNA message to announce the
extenal sub-networks before. 

>From the olsrd-gui on gateway A, I can see the route
is there but it is not in the routing table. For
example, I external subnet prefix is
2001:5c0:840a:100:1::/80 and I can see there is a
route to 2001:5c0:840a:100:1:: on the olsrd-gui on A,
but when I do route -A inet6, it does not give me the
route. 

That is where I stuck and start to find some way to
solve it. But it seems I am not lucky enough to get it
work with my current configuration. 

The reason why I don't want to run olsr on the client
PC is that I want to make it easy for the client.
Actually I am trying to have the olsr mobile routers
as the gateway of several small mobile networks and
the mobile routing mechanism is supposed to be
transparent to the client PCs. 

The current problem is the route from the Internet
gateway to the client PC on the external network
cannot be found. I can see the packets is routed to
the gateway but the gateway just cannot reply because
the route is not there.

Any idea on the problem? Do you think using HNA to
declare the external network is a good idea? If yes,
What may be the cause of the routing table problem?

Thanks in advance and Merry Christmas!

Regards,

Xia Yang
