I read from the book that ASBR is used to join different routing domain.
However, i notice that there is a router in my company used only ospf but receive LSA Type 1, 2, 3,4 and 5 (External) in the database.
However this router is consider ASBR when i issue "Show ip protocols"
What is the theory behind? Or can i say if the router is receiving LSA type 5, it is consider a ASBR router. I am confusing now. Thanks!
