NTP Troubleshooting Capstone

Bundle lab · $29.99

Advanced NTP troubleshooting on a two-router /30. R2 never synchronizes its clock. Use show commands to diagnose, then correct the design intent so R2 deterministically references R1, and R1 is an authoritative time source at the agreed stratum. The starter ships with a pre-broken NTP configuration already applied; your job is to find and fix two independent faults.

Learning objectives

• Diagnose NTP non-synchronization on IOS using show ntp status and show ntp associations
• Establish an IOS router as an authoritative NTP clock at a chosen stratum
• Point an NTP client deterministically at the correct upstream source
• Validate deterministic configuration without waiting for full convergence

Troubleshooting focus

• R2 shows unsynchronized status and never transitions to a valid stratum
• NTP associations indicate an unreachable or invalid server
• A time source exists on-link but is not authoritative
