That optiona is not available in ospf. If you have more than one ABR
then you may configure 'area x range' on one router and leave other ABR
routers as such,..that can have both component and summary avl. Other
option could be configure 'area range' for component routes also and
that way you have both avl from a single ABR.

Thanks
