The following table describes the view-only fields on the page.

Description

Field

A definition of the switch’s capabilities for the area, including whether or not
AS-external-LSAs are flooded into or throughout the area. If the area is a stub area,
one of the following external routing capabilities can display:

• Import External LSAs: Imports and propagates external LSAs.

• Import No LSAs: Does not import and propagate external LSAs.

If the area is

not

a stub area, the only option is Import No LSAs.

External Routing

The number of times that the intra-area route table was calculated using this area’s
link state database. (This is typically calculated using Dijkstra’s algorithm.)

SPF Runs

The total number of area border routers that re reachable within this area. This is
initially zero, and is calculated in each SPF pass.

Area Border Router
Count

The total number of link state advertisements in this area’s link state database, excluding
AS external LSAs.

Area LSA Count

The 32-bit unsigned sum of the link state advertisement checksum contained in this
area’s link state database. This sum excludes external (LSA type 5) link state
advertisements. You can use the sum to determine if a change occurred in the link
state database of the switch, and to compare the link state database of two devices.

Area LSA Checksum

The number of LSAs on this area’s flood list.

Flood List Length

The summary LSAs that are imported into this area.

Import Summary LSAs

Add an OSPF stub area

A stub area is a controlled area that does not allow external routes from outside the
OSPF network.

To add an OSPF stub area:

1. Launch a web browser.

2. In the address field of your web browser, enter the IP address of the switch.

If you do not know the IP address of the switch, see Log in to the main UI with a web
browser on page 27 and the subsections.
