OSPF Area Details
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.
Router ID
Displays the router ID assigned for this OSPF connection. The router is a level three Internet Protocol
packet switch. This ID must be established in every OSPF instance. If not explicitly configured, the
highest logical IP address is duplicated as the router identifier. However, since the router identifier is
not an IP address, it does not have to be a part of any routable subnet in the network.
Neighbor Priority
Displays each listed neighbor’s priority in respect to becoming the designated router managing the
OSPF connection. The designated router is the router interface elected among all routers on a
particular multi-access network segment.
IF Name
Lists the name assigned to the router interface used to support connections amongst OSPF enabled
neighbors.
Neighbor Address
Lists the IP address of the neighbor sharing the router interface with each listed router ID.
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.
