[support] RAs leaking into adjacent wifi networks

[Georgopoulos, Panagiotis]

Hello all,

 

                To be fair, this is strictly not a nepl related question but
since you have done many experiments with madwifi APs and clients I just
thought to ask as it has started getting annoying. Apologies to the list.

 

                In my nepl running testbed I have numerous madwifi APs and
clients to try and simulate real life scenarios of MR roaming from one
network to another doing bindings with their respective HAs. I recently have
started seeing situations where a client (ie. a sta interface in a MR)
although being connected to e.g. AP1, receive inadvertently RA from AP2.
Unfortunately this makes the interface configure an additional address from
the network prefix of AP2 and brake the bindings which from this point on
cannot achieve. 

 

The client interfaces are configured using iwconfig athx essid "ssid-name"
(NOT any) so it is very weird that they hear RAs from adjacent networks (I
can confirm in wireshark that they hear RAs from a network that they are not
connected to). Let me also note here, that wireshark logs like 50 RAs from
the network that they are connected to and then only one from an adjacent
network that brake things. 

 

Unfortunately this problem is happening very frequently lately and I was
wondering whether there is anyone who experienced this in the past and
whether there is a solution to it? Is there any obvious configuration issue
or something that I might have overlooked causing this problem?

 

Thanks a lot in advance,

Panos
