BGP/OSPF router-id mismatch and the BGP synchronization rule

Hi all,

I know this is not common these days, as BGP synchronization is turned off by default in recent ios versions. However, I was wondering if anyone knows why a Cisco router considers an OSPF route not synchronized, if the OSPF router id and BGP router id don't match.

Is this an implementation-specfic thing or is there some protocol design thinking behind it?
