I think in this case the rule of synchronization still holds because the BGP
routes A is advertising have been successfully installed in the BGP table of
B. The routing table (which is a separate entity from the BGP table, of
course) does not install the BGP routes because of the lower AD of OSPF
(which you have already discovered in your second example). In other words,
what you observed is not a failure of synchronization because a successful
update of the BGP table does not necessarily mean the routing table must
also reflect that update. In your first example router B should be able to
advertise its IBGP routes to the external AS.
