Consider the following topology:
l0 l1 A ---- B ==== C l2where --- is a single link (l0) and === are two links (l1 and l2).
Now imagine that the administator wants to dedicate the link l2 to the communication between B and C, for whatever reason. It is fairly easy to set netfilter rules to that effect, for instance.
It would be possible to do what you want. Simply don't add the l2 interfaces to BATMAN, put IP addresses from a different subnet on the interfaces, and B and C can use the link l2 for themselves, and use the bat0 interface for access to the mesh subnet.
This was of course a simplified example.
What if there are an arbitrary number of nodes between B and C instead of a direct link?
l0 l1 A ---- B ---------- C Example: \ / I want to restrict the link l1 to communication D -- E -- F between A and C. (Nice frying-pan, isn’t it? ;-)
I love ASCII-art, I can build arbitrarily complex situations (and we actually use this kind of stuff with babel on wifi.pps.jussieu.fr). Your solution doesn’t scale, it only pushes the problem outside of batman.
Best,
