Guys,

Ospf router IDs are local to the router. (My assumption).

However should there every be a scenario where the router ID learned under a 
particular interface is not local to the router.

See below.

10.68.63.129 is from a connected router, but not the directly connected network.

router ospf 10
 router-id 10.68.0.65
 log-adjacency-changes
 auto-cost reference-bandwidth 10000
 redistribute static subnets route-map redis-statics-routemap
 redistribute ospf 65485 subnets route-map NEON_TO_DCLAN
 redistribute bgp 65399 subnets route-map ITC_DCLAN
