Hello!

Can you clarify what specific version of IOS 15.1 you're running on this 1941 router? It might be a result of a known defect CSCsy28636.

Thank you!

USING LATEST PACKET TRACER

[Martin L]

it is probably a bug in IOS or PT software sim; glitch; or left over from other ospf configs that have been removed;  Try clear ip osp process to see if that goes away.

I assumed this is router 4 on the picture, right?

Hello,

is this a 2901 router in Packet Tracer ? Post the zipped .pkt file. It could also just be a bug in Packet Tracer...

[Richard Burts]

Perhaps the output of show ip ospf might be helpful. I agree that it sounds like there might have been a different ospf area configured and then removed. So I agree that clearing the ospf process might be helpful.

[Farhan64]

Yes, I think it was a bug, in morning it automatically says display as
