4.4.4.6 Area Range
This is OSPF area range configuration table. It is used to summarize the intra area paths from a specific address range in one
summary-LSA(Type-3) and advertised to other areas or configure the address range status as 'DoNotAdvertise' which the
summary-LSA(Type-3) is suppressed. The area range configuration is used for Area Border Routers (ABRs) and only
router-LSAs(Type-1) and network-LSAs (Type-2) can be summarized. The AS-external-LSAs(Type-5) cannot be summarized
because the scope is OSPF autonomous system (AS). The AS-external-LSAs(Type-7) cannot be summarized because the
feature is not supported yet.. The screen in Figure 4-4-4-6 appears.
