Is it possible to force the path of layer 2 traffic in a mesh? In
other words, if we have laptops A, B and C in a room, all within radio
range, can we force A to talk to C via B?
Yes: http://wiki.laptop.org/go/Mesh_Forwarding_Table
Actually, that page doesn't explain how to manipulate the table.
That's described here:
http://wiki.laptop.org/go/Wireless_Driver_README
FWT (Forwarding Table) Commands:
The forwarding table (FWT) is a feature used to manage mesh network
routing in the firmware. The FWT is essentially a routing table that
associates a destination mac address (da) with a next hop receiver
address (ra). The FWT can be inspected and edited with the following
iwpriv commands, which are described in greater detail below.
Eventually, the table will be automatically maintained by a custom
routing protocol.
iwpriv ethX fwt_add [parameters]
iwpriv ethX fwt_del [parameters]
iwpriv ethX fwt_lookup [parameters]
iwpriv ethX fwt_list [parameters]
iwpriv ethX fwt_list_route [parameters]
iwpriv ethX fwt_list_neigh [parameters]
iwpriv ethX fwt_reset [parameters]
iwpriv ethX fwt_cleanup
iwpriv ethX fwt_time
fwt_add
This command is used to insert an entry into the FWT table. The list
of
parameters must follow the following structure:
iwpriv ethX fwt_add da ra [...]
The different parameters are:-
da -- DA MAC address in the form 00:11:22:33:44:55
ra -- RA MAC address in the form 00:11:22:33:44:55
