CCNA Tutorial: The OSPF Router ID (RID)

http://www.thebryantadvantage.com/CCNACertificationExamTutorialOSPFRouterIDRID.htm

When determining the Router ID (RID) of an OSPF-enabled router, OSPF will always use the numerically highest IP address on the router’s loopback interfaces, regardless of whether that loopback is OSPF-enabled.

What if there is no loopback? OSPF will then use the numerically highest IP address of the physical interfaces, regardless of whether that interface is OSPF-enabled.
