OSPFv2 selects the router ID based on the highest IP address of active loopback interfaces if they are present. In this scenario, the loopback interfaces have IP addresses 192.168.1.1 and 10.0.0.1. The highest IP address among these is 192.168.1.1, so OSPFv2 will use this as the router ID. If there were no loopback interfaces, it would select the highest IP address from active physical interfaces.
