[OLSR-users] OLSR over managed links

[Thomas Lopatic]

Hi Sven-Ola,

[managed mode, OLSR node acting as access point is 104.0.2.1, OLSR nodes
acting as clients are 104.0.2.111 and 104.0.2.222]

Hmmm. I am not sure whether I understand the problem. That's how I see the
managed mode scenario: Suppose that client #1 sends a packet to client #2.
It does so by sending the packet to the access point, which then relays it
to client #2. So, on layer 3 and higher the two clients see each other,
whereas on the lower layers they don't. In other words: Judged from layer
3, there IS a direct connection between the two clients.

So, I'd say that from a layer-3 perspective that's the "each node sees
each other node" case. Here's what I'd expect the olsrds on the nodes to
behave like:

* 104.0.2.1 - sees broadcasts by both clients
* 104.0.2.111 - sees broadcasts by AP and other client (relayed by AP)
* 104.0.2.222 - sees broadcasts by AP and other client (relayed by AP)

So, as everybody receives everybody else's HELLO broadcasts, everybody is
everybody else's neighbour. This should work.
