13.3.14.3 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 System from the navigation pane (on the left-hand side of the screen), expand the default node and select an access
point for statistical observation.
3. Select OSPF.
4. Select the Area Details tab.
Request Count Lists the connection request count (hello packets) to connect to the router interface, discover
neighbors and elect a designated router.
Retransmit Count Lists the connection retransmission count attempted in order to connect to the router interface,
discover neighbors and elect a designated router. A designated router (DR) is the router interface
elected among all routers on a particular multi-access network segment, generally assumed to be
broadcast.
Dead Time Lists the dead time between neighbors in the network topology that are currently utilizing the listed
router ID.
Self Neighbor
State
Displays the self-neighbor status assessment used to discover neighbors and elect a designated
router.
Source Address Displays the single source address used by all neighbor routers to obtain topology and connection
status. This form of multicasting significantly reduces network load.
Summary Count Routes that originate from other areas are called summary routes. Summary routes are not flooded
in a totally stubby or NSSA totally stubby area.
