Ok.

A throw route is no problem by itself. It only means that the Linux kernel=
=20
will leave the current table to check the next one for a suitable routing=20
entry.=20

If you are interested in understanding the routing techniques used by batma=

Does each node announce the "local wifi net" via HNA ? You will need these=
=20
announcements to make the routing towards this addresses work. As soon as=20
batmand knows that it is responsible for a certain IP address space it will=
=20
add the appropriate routing entries for you.
Again, we have a document describing the process:

Cool! Good luck with your experiments. :-)
