Which of the following statements is false about OSPF area partition?
The statement that only area border routers (ABRs) can function as autonomous system boundary routers (ASBRs) is false. An ASBR can be any OSPF router that is injecting external routes into the OSPF domain, not necessarily an ABR. This means that an internal router can also be an ASBR if it is connected to external networks and redistributing that information into the OSPF network.
