OSPF Router ID

Hello Arindom.

I answered a similar question that you had in this thread. Please take a look

How to configure OSPF for CCNA students

Hello Arindom Indeed with the config as you have it set up, the router ID should become 2.2.2.2 since it is the highest loopback ID. However, 192.168.23.2 does remain the router ID even after the clear ip ospf process command. The only thing i can think of is that you have the router ID explicitly configured in the OSPF process as 192.168.23.2 and this is why it is not changing. Please confirm that you have no configured router ID in the OSPF configuration. If all else fails, try rebooting …

I hope this has been helpful!
