My router is running ospf with highest interface IP. I configed loopback and clear ospf process, but router ID did not changed. I reloaded router, still same.Why?
When I use Router-ID command, it get changed finally.
Curious why reset ospf process or reload does not change the router ID? BTW, my loopback @ is not been used by other router as router ID.
Thank you very much for your help.
it must be protection for stability; when router reboots and router id has changed, it will be hard to troubleshoot remotely.
but according to books, it should change after reboot;
changing router-id with command, it should change after clearing ospf process only; no rebooting required;
