Area Range
This page displays the 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.
