Translator Stability Interval - Enter the translator stability interval of the NSSA. The stability interval is
the period of time that an elected translator continues to perform its duties after it determines that its
translator status has been deposed by another router. Valid values range from 0 to 3600.
No-Redistribute Mode - Select enable or disable from the pulldown menu. If you select enable learned
external routes will not be redistributed to the NSSA.
Non-Configurable Data
Area ID - The OSPF area. An Area ID is a 32 bit integer in dotted decimal format that uniquely identifies
the area to which a router interface connects.
Aging Interval - The Link State Advertisement (LSA) aging timer interval.
External Routing - A definition of the router's capabilities for the area, including whether or not
AS-external-LSAs are flooded into/throughout the area. If the area is a stub area, then these are the
possible options for which you may configure the external routing capability, otherwise the only option
is "Import External LSAs".
Import External LSAs - Import and propagate external LSAs
Import No LSAs - Do not import and propagate external LSAs
Authentication Type
Currently set to 'None'.
SPF Runs - The number of times that the intra-area route table has been calculated using this area's
link-state database. This is typically done using Dijkstra's algorithm.
Area Border Router Count - The total number of area border routers reachable within this area. This
is initially zero, and is calculated in each SPF Pass.
Area LSA Count - The total number of link-state advertisements in this area's link-state database,
excluding AS External LSAs.
Area LSA Checksum - The 32-bit unsigned sum of the link-state advertisements' LS checksums
contained in this area's link-state database. This sum excludes external (LS type 5) link-state
advertisements. The sum can be used to determine if there has been a change in a router's link state
database, and to compare the link-state database of two routers.
Mode - This field tells you whether the area is or is not a stub area. If the area may be a stub area, a
'Create Stub Area' button will be displayed. If you have configured the area as a stub area a 'Delete
Stub Area' button will be displayed. Otherwise neither button will be displayed.
Type of Service - The type of service associated with the stub metric. The switch supports Normal
only.
Translator Status - The field tells you the translator is enabled or disabled.
Command Buttons
Create Stub Area - Configure the area as a stub area.
