It's worth noting that C's don't need actual IP address space assigned to the router-id for OSPF. It's just an arbitrary value; it's probably better karma to set it to whatever you want (maybe something that doesn't look like an IP address).
RFC 2328: Router ID A 32-bit number assigned to each router running the OSPF protocol. This number uniquely identifies the router within an Autonomous System. CCO: <http://www.cisco.com/en/US/products/sw/iosswrel/ps1839/products_command_reference_chapter09186a008010a39c.html#wp1049279> Usage GuidelinesYou can configure an arbitrary value in the IP address format for each router. However, each router ID must be unique.
If this command is used on an OSPF router process which is already active (has neighbors), the new router-ID is used at the next reload or at a manual OSPF process restart. To manually restart the OSPF process, use the clear ip ospf command.
