OSPF Area Details
OSPF
An OSPF network is subdivided into routing areas (with 32 bit area identifiers) to simplify
administration and optimize traffic utilization. Areas are logical groupings of hosts and networks,
including routers having interfaces connected to an included network. Each area maintains a
separate link state database whose information may be summarized towards the rest of the
network. An OSPF Area contains a set of routers exchanging Link State Advertisements (LSAs) with
others in the same area. Areas limit LSAs and encourage aggregate routes. Areas are identified by
32-bit IDs, expressed either in decimal, or octet-based dot-decimal notation.
To view OSPF area statistics:
1. Select the Statistics menu from the Web UI.
2. Select a Wireless Controller node from the left navigation pane.
3. Select OSPF from the left-hand side of the UI.
4. Select the Area Details tab.

The Area Details tab describes the following:
OSPF Area ID Lists the connection request count (hello packets) to connect to the router interface, discover neighbors and
elect a designated router.
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.
