You have decided to use ACLs on your router to restrict NTP traffic between networks. Specifically, you want to allow only the server with an IP address of 172.17.8.1 to synchronize time with an NTP time provider with an IP address of 10.0.0.1 on a different network. The NTP protocol runs on UDP port 123. To accomplish this, you create the following ACL on the router connecting the two networks.
