The updated configuration is sent to the switch. Configuration changes take effect 
immediately.
The following table describes the nonconfigurable data that is displayed.
Configure the OSPF Area Range
Configure the OSPF area range: 
1. 
Prepare your computer with a static IP address in the 169.254.100.0 subnet, for 
example, 169.254.100.201.
2. 
Connect an Ethernet cable from an Ethernet port on your computer to an Ethernet port on 
the switch.
3. 
Launch a web browser.

Table 148.  OSPF NSSA Area Configuration 
 
Field
Description
SPF Runs
The number of times that the intra-area route table was 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' LSA 
checksums contained in this area's link state database. This sum 
excludes external (LSA type 5) link state advertisements. The sum can 
be used to determine if there was a change in a router's link state 
database, and to compare the link state database of two routers.
Translator State
This field displays if and how the NSSA border router translates Type 7 
into Type 5. Possible options are as follows:
• 
Enabled
. The NSSA border router’s translator role is set to always.
• 
Elected
. The candidate NSSA border router is translating Type 7 
LSAs into Type 5.
• 
Disabled
. The candidate NSSA border router is not translating 
Type 7 LSAs into Type 5.
