What this guide covers
Diagnose and fix OSPF duplicate router-id on a Dell device (Dell OS10 / SmartFabric OS).
Most likely cause + fix
Two routers using the same router-id. Set router-id explicitly.
Spot the symptom
show interface status
# Use the Dell OS10 / SmartFabric OS equivalents of:
# show ip route / show route
# show ip bgp summary / show bgp summary
# show ip ospf neighbor / show ospf neighbor
# show log | include BGP|OSPF
When the issue persists
- Capture show tech-support | save tftp://10.10.1.100/tech.txt and open a Dell ProSupport case.
- Cross-reference https://www.dell.com/support/manuals/ for known issues in your release.
Frequently asked questions
Will this work on my specific Dell OS10 / SmartFabric OS version?
The procedure reflects current Dell OS10 / SmartFabric OS behaviour. Older releases may need minor syntax adjustments, use the CLI help (? or tab-completion) to verify.
Should I open a Dell ProSupport case immediately?
Open one if you suspect hardware failure or the symptom persists after a maintenance-window reload. Make sure your support entitlement is active first.
Where can I find the Dell official documentation?
https://www.dell.com/support/kbdoc. search the product family + feature name.
Is this procedure safe in production?
Test in a lab or maintenance window first. Capture pre-change state so you can roll back.

Why this matters for your day-to-day
A Dell: device that's misbehaving costs more than the fix itself: lost productivity, missed calls, security risk, even safety risk in some categories. Treating the symptom quickly with a documented procedure is cheaper than letting it persist. The steps above are written to get you back to working in under an hour where possible, and to flag clearly when escalation is the right call.
Quick triage
A few things to confirm so the Dell: device fix goes cleanly:
- Latest firmware downloaded if you're going to update.
- Warranty + support contract status checked, opening sealed parts may void it.
- Backup of current configuration (where applicable) taken.
- Spare parts on hand if you anticipate replacement.
- Adequate workspace, lighting, and time: rushing causes regressions.
Confirm it stuck
On a Dell: device, the test is rarely "reboot and see". Use this list:
- Active reproduction: trigger the original failure path on purpose.
- Indirect reproduction: do an activity that would expose the same subsystem.
- Status indicator review: every LED / display / app status should be green.
- 24-hour soak: leave the device under normal load overnight; check the next morning.
- Telemetry check: review the device or app's diagnostic log for new error entries.
When to call Dell: support instead
Escalate if:
- The same symptom returns within 24 hours of a clean fix.
- You see physical damage (burn marks, swollen battery, cracked PCB).
- The device is in warranty and a hardware replacement is the cheaper outcome.
- Repair requires specialised tools you don't own (alignment jigs, calibration software).
- Following the official path keeps the warranty intact, which matters more than the time spent.
More frequently asked questions
Will this void my warranty?
Applying official firmware updates and following the user manual will not affect warranty. Opening sealed components, jumping safety circuits, or using third-party parts can void warranty in most jurisdictions.
What if my model isn't exactly the same revision?
Cross-check the model code on the rating plate against the manufacturer support page. Major firmware generations sometimes shift the menu path; the option is usually under a similarly-named section.
Will the procedure work on the international variant?
Some features and firmware paths are region-locked. Check the model spec sheet to confirm your variant supports the menu option referenced. If you're outside the US/EU, look for the regional support portal.
How long does this fix usually take?
Most users complete the steps in 20-45 minutes the first time, and 5-10 minutes on subsequent runs once the menu paths are familiar.
Why is this happening on a brand-new unit?
Out-of-box defects do occur. If you've owned the device under 30 days and the symptom persists after a factory reset, escalate to the seller for replacement under DOA terms before opening a manufacturer support case.
