What you have should be sufficient for that. However, you should really
supply a filename as an additional field in that definition, otherwise
named will have to download a new copy of the zone every time it
reloads/restarts, and if it reloads/restarts while the master is
unavailable, you'll be completely SOL until it comes back up again. When
you supply a filename, a slave copy of the zone is written to disk
whenever it changes, so that the slave can operate more autonomously.
