Local Time with Timezones over NTP

Bundle lab · $29.99

Two-router /30 point-to-point lab. R1 is an authoritative UTC NTP master (stratum 3). Configure R2 as an NTP client to R1 and display local time in MST/MDT while remaining synchronized to UTC. Reinforces that NTP distributes UTC and the router applies timezone/daylight-saving only to presentation.

Learning objectives

• Configure a Cisco IOS router to synchronize its clock using NTP to a reachable authoritative master
• Apply a local timezone offset for display without altering the underlying UTC timebase
• Enable recurring daylight-saving time (summer-time) so the displayed time automatically adjusts
• Verify NTP status and local-time presentation with show commands

Troubleshooting focus

• Confirm L2/L3 reachability on the /30 point-to-point link before blaming NTP
• Understand that NTP distributes UTC; verify timezone/summer-time for local display
• Allow time for NTP to select and mark a source; grade by configuration presence, not by convergence
• Check for typos in timezone sign (west of UTC is negative) and daylight-saving rule syntax
