Hi guys, I'm writing a short report about the actual behaviour of b.a.t.m.a.n. in case of client roaming between bat-nodes.
I was wondering what could happen in a particular (but not so unusual) situation:
take a network made up of several nodes, and 2 IP gateways, say X and Y. These 2 gws are advertising themself as gw (via the gw-mode). Now we have two nodes A and B which respectively recognize as gw X and Y (A recognizes X and B recognizes Y, where recognize means "to have such gw as best gw"). Each gw runs a dhcp server which assigns itsself as default ip route.
Now, what would it happen if a client roams from A to B and sends a new dhcp request (cause the lease time has expired) so changing the default gw from X to Y? The established connections will stop to work.
I think that this is a classical level 3 issue in the hand-off procedure. What do you think about this problem? Am I missing something?
Thank you all :)
