BIND uses TCP for zone transfers by default. It doesn't fall back to
UDP, so you don't have to configure anything.
In general, all name server software I know of, uses TCP for zone
transfers. UDP is not recommended, although some implementations, such
as NSD, provide the option to do tranfers over UDP (and strongly urge
the use of TSIG in that case).
