DNS Express and Zone Transfers

For those that are using this article as a resource for getting familar with BIG-IP DNS and therefore are using the same setup (BIG-IP running BIND as the master and DNS Express as slave on the same machine), one short hint:

To be able to automatically update DNS Express through NOTIFY-Messages from the local BIND, you have to use the following command in the configruation of named.conf, otherwise it won't work:

also-notify {
    ::1 port 5353;
};

Also notice that it really needs to be ::1, since 127.0.0.1 did not work for me, even if I was just using IPv4 for all the listeners and stuff. See also the following link, section "Configuring local BIND to send NOTIFY messages to DNS Express":
