This short script create filters. This script can create only about 1789
filters. After that we have this:
(...)
f9 10.0.7.249
fa 10.0.7.250
fb 10.0.7.251
fc 10.0.7.252
fd 10.0.7.253

After this I can't create any more filters on this device. What should I
do when I have 10 subnets or more? I want to create more filters. Who
knows how?
Below this text we have next example... creating filters well, but it's
too slow!
for ((j=0; j<=10; j++))
do
for ((i=0; i<=255; i++))
do
$TC filter add dev imq0 protocol ip parent 1:0 prio 4 u32 match
ip src 10.0.$j.$i flowid 1:10
echo "10.0.$j.$i"
done
done
I need more powerful solution. Need some help... Any suggestions?
