Generate BGP filters with BGPQ3

Build it:

cd /tmp
wget http://snar.spb.ru/prog/bgpq3/bgpq3-0.1.31.tgz
tar -xvzf bgpq3-0.1.31.tgz
cd bgpq3-0.1.31/
./configure --prefix=/opt/bgpq3
sudo mkdir -p /opt/bgpq3/bin
sudo make install

Generate filter list by ASN (actually you could use AS-SET here too):

This toolkit supports so much options for diffrent vendors (and even json!).

Great thanks to author, Alexander Snarski.
