Hi, is there a way to retrive the topology of the 802.11 mesh network?

thank you, Gabriel

Don't think that we have such a tool.

But you can collect one-by-one by using mpath dump, probably need to do this using wired interface.

Thomas had a hack that used ipv6 all-nodes broadcast ping and then
dumped the neighbor table - if ipv6 is used you can do that. Otherwise
you could do something like Chun-Yeow said (hopefully github doesn't mess it
up too much):

#!/bin/bash

hack to generate graphviz output from mpath table

dev=wlan0
echo "digraph {"
for host in zotac0 zotac2 zotac3; do
local_mac=$(ssh root@$host "iw dev $dev info" | awk '/addr/{print $2}')
ssh root@$host "iw dev $dev mpath dump" |
egrep '^(([0-9a-f]:){5}[0-9a-f]) \1' |
awk '{print " "'$local_mac'" -> "" $2 "" [label="" $5 ""]";}'
done
echo "}"
