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.
