NTP Server via DHCP Server


i'm interested if it's possible to set the NTP server via DHCP on an 2901 Router with 15.2(2) image.

i configured the interface gigabit 0/0 as dhcp client. The DHCP Server sends to me DNS, Default GW and NTP. All is working fine, but the NTP will not be configured. i tried to add an DHCP option request, but there is no NTP (42) value

Router2901(config-if)#ip dhcp client request ?
