At the moment it requires user to configure every network one by one. and it doesn't support configuring ip6tables 

cat >/etc/cni/net.d/10-mynet.conf
{
        "cniVersion": "0.2.0",
        "name": "mynet",
        "type": "bridge",
        "bridge": "cni0", 
        "ipam": {
                "type": "host-local",
                "subnet": "2001:db8::/96",
                "routes": [
                        { "dst": "::/0" },
                        { "dst": "2001:db8::/96" }
                ]
        }
