Simon,
I used to test BGP sync with OSPF for half a day. It shows something not quite
suitable with the theory. SYNC status differ according to topology, route type,
area and reflector. So I think whenever you need BGP select and install a rout
e but it does not sync with OSPF, use no sync. Or simply, use no sync everywher
e.
