Hi Jens

The script i just used is:

# add one if per 3 second and give output, also monitor dmesg
dmesg -w &
for i in `seq 1 255`; do
    # one interface
    ip link add gre$i type gretap local 192.168.99.1 remote 192.168.3.$i ttl 255 dev lan1
    ip link set up dev gre$i
    batctl if add gre$i
    # another inf
    ip link add grex$i type gretap local 192.168.99.1 remote 192.168.4.$i ttl 255 dev lan1
    ip link set up dev grex$i
    batctl if add grex$i
    echo -n $(uptime|cut -d"," -f4-) $(ifconfig lan1|grep TX\ p) $i
    sleep 3
done

So this adds two interfaces per 3 seconds to bat0.

root@wrt1900ac:~# batctl if
grex122: active
gre123: active
grex123: active
gre124: active
grex124: active
gre125: active
grex125: active
gre126: active
...
grex119: active
gre120: active
grex120: active
gre121: active
grex121: active
gre122: active


root@wrt1900ac:~# batctl if | wc
    344     688    5116

So i have 344 interfaces in the mesh. No memory problems reported.

   Andrew
