Good question !

My normal connectivity to destination network is via default route to
internet. So the destination network network, under normal circumstances is
not in the routing table. When the internet connection went down, ISDN
kicked in and OSPF sent all routes from all the branch router to the caller
and provided continued connectivity. When internet came back up, these route
needs to go away.
