R1 is configured with the default configuration of OSPF. The loopback interface is not configured.
Which address will the OSPF process select as the router ID?
192.168.1.1
The router ID can be manually assigned. If it isn't manually configured:
- The highest IP address assigned to a loopback (logical) interface.
- If a loopback interface is not defined, the highest IP address of all active physical interfaces will be chosen.
