NETGEAR M4350-24F4V 24-Port 10G SFP+ Managed AV Network Switch - Manual (Page 468)

• Comparable Cost: External type 1 metrics that are comparable to the OSPF
metric
• Non-comparable Cost: External type 2 metrics that are assumed to be larger
than the cost of the OSPF metric.
9. From the Translator Role menu, select the role of the NSSA:
• Always: The switch assumes the role of the translator when it becomes a border
router.
• Candidate: The switch participates in the translator election process when it
attains border router status.
10. In the Translator Stability Interval field, enter the period during which the switch
extends its translator role after another device becomes the translator.
The range is from 0 to 3600 minutes.
11. From the Redistribute Mode menu, select if learned external routes are redistributed:
• Enable: The NSSA ABR distributes learned external routes to the NSSA.
• Disable: The NSSA ABR does not distribute learned external routes to the NSSA.
12. Click the Add button.
The area is added as an NSSA area.
13. To save the settings to the running configuration, click the Save icon.
The following table describes the view-only fields on the page.
Description Field
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 (Type 5 LSAs) 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
This field displays if and how the NSSA border router translates Type 7 LSAs into Type
5 LSAs:
• 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
LSAs.
• Disabled: The candidate NSSA border router is not translating Type 7 LSAs into
Type 5 LSAs.
