An OSPF router does not have a router ID configured.
In this scenario, which statement is correct about the router ID?
In OSPF configuration on Junos OS, if a router ID is not explicitly configured, the router will use the IP address assigned to the loopback interface as the router ID. If there is no loopback interface configured, then the highest IP address assigned to any active physical interface will be used.
The router identifier is used by BGP and OSPF to identify the routing device from which a packet originated. The router identifier usually is the IP address of the local routing device. If you do not configure a router identifier, the IP address of the first interface to come online is used. This is usually the loopback interface. Otherwise, the first hardware interface with an IP address is used.
the B is correct
