Figure 13-52 Access Point - OSPF Area Details tab
The Area Details tab describes the following:
OSPF Area ID Displays either the integer (numeric ID) or IP address assigned to the OSPF area as a unique
identifier.
OSPF INF Lists the interface ID (virtual interface for dynamic OSPF routes) supporting each listed OSPF area
ID.
Auth Type Lists the authentication schemes used to validate the credentials of dynamic route connections and
their areas.
Total LSA Lists the Link State Advertisements (LSAs) of all entities using the dynamic route (in any direction)
in the listed area ID.
Router LSA Lists the Link State Advertisements of the router supporting each listed area ID. The router LSA
reports active router interfaces, IP addresses, and neighbors.
Network LSA Displays which routers are joined together by the designated router on a broadcast segment (e.g.
Ethernet). Type 2 LSAs are flooded across their own area only. The link state ID of the type 2 LSA
is the IP interface address of the designated route.
Summary LSA The summary LSA is generated by ABR to leak area summary address info into another areas. ABR
generates more than one summary LSA for an area if the area addresses cannot be properly
aggregated by only one prefix.
ASBR Summary
LSA
Originated by ABRs when an ASBR is present to let other areas know where the ASBR is. These
are supported just like summary LSAs.
