Restricting NTP with an access-group

Configure a Cisco IOS router as an authoritative NTP master and restrict which clients it will serve using an NTP access-group with a standard ACL. One shared LAN (no routing) connects three routers through a Layer-2 switch. Only R2 is authorized to receive time from R1; R3 is denied. Learners deploy, verify, and troubleshoot the access-group behavior.
