NTP
Configured Network Time Protocol (NTP) across routers and a server to synchronize clocks in a Cisco Packet Tracer network. The lab included manual time and time zone setup, NTP client-server relationships, authentication, and fallback configurations for accurate timekeeping.
Tools:- Cisco Packet Tracer
- Router CLI
- NTP Show Commands
- Clock Configuration Commands
- Fast-Forward Simulation
Skills Demonstrated:- Manually setting system time and time zones on Cisco routers
- Configuring routers to synchronize with external NTP servers
- Enabling NTP authentication and defining trusted keys
- Setting up fallback NTP master role on routers using NTP master command
- Synchronizing downstream routers to an authenticated NTP source
- Verifying NTP associations and stratum levels with show commands
- Using NTP update-calendar to sync hardware clock (where supported)
- Understanding limitations of Packet Tracer regarding calendar and NTP features
