Translator Role - Select Always or Candidate from the pulldown menu. A value of always
will cause the router to assume the role of the translator when it becomes a border router
and a value of candidate will cause the router to participate in the translator election
process when it attains border router status.
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.
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
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.
Interface 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.
Command Buttons
Create Stub Area - Configure the area as a stub area.
