There is no $GENERATE command available on IPv6, therefore you must specify every forward and reverse entry in bind manually. You could however use the $INCLUDE statement to include a range you have generated with a script. I will post a script here to generate IPv6 forward and reverse files you can include in bind.

generate-forward-ipv6.sh

#!/bin/sh
# generate 250 of these lines:
# ip20-042     IN      AAAA    2001:dead:beef:14::2a
# where 20(0x14) is the vlanid and 42(0x2a) is the host part
if [ -z $1 ]; then
 echo "usage: $0 <vlanid>"
 exit
fi
vlanid=$1
counter=1
while [ $counter -le 250 ]; do
 printf "ip$vlanid-%03d\tIN\tAAAA\t2001:dead:beef:%x::%x\n" $counter $vlanid $counter;
 counter=`expr $counter + 1`
done
