Mohamed,
If I have understood this correctly, you need to create an access-list on
R1(the NTP master) and apply this access-group to the ntp.
The below configuration allows R1 to service only the requests coming from
172.16.12.1 to 172.16.12.255.
R1
access-list 11 permit 172.16.12.0 0.0.0.255
!
ntp access-group serve 11
ntp master 2
The NTP server will receive the time requests from other devices, if they
are configured with R1 as the NTP server, but would not service them. If you
run a an ntp debug you will see the following only to the devices, the NTP
server is servicing the time requests.
NTP: stateless xmit packet to 172.16.12.1
HTH,
Shine
