When I put "clear ip ospf process" after changing router-id on GNS3 , I got the bug
that there was the output of "show ip ospf neighbor" but there was no ospf route . like following output
after that , again I did put " clear ip ospf process " without any changes after 2 minutes .
I could see the output of " sh ip route ospf " .
Is this known bug on GNS3 ? Or
Is this the known issue that it happens sometime on real Cisco routers ?
I dont have the real labo . so I feel so insecure .
Here is the output after did put " clear ip ospf process "
R3#sh ip ospf nei

Have you ever have the issue on your real labo or actual environment ?
