ospf default route

Hi ,

based on follwoing config , intent is to track the route and originate a
default route .

router ospf 1
default-information originate always route-map TRACK_LINK_TO_BB1
!
ip prefix-list LINK_TO_BB1 seq 5 permit 54.1.1.0/24
!
route-map TRACK_LINK_TO_BB1 permit 10
match ip address prefix-list LINK_TO_BB1

quesiton : 54.1.1.0/24 is FR subnet . how does ospf track this .

it is a connected route that never disappears from routing table
regardless of layer 2 status .

how ospf process determines this route is active ? does it checks the
layer two status ? or does it check if route is availble in routing
table ? in later case the route is always available as connected route
