OSPFv3 Area Index Configuration Options (continued)
Command Syntax and Usage
area <0‐2> stability­interval <1‐255>
Configures the stability interval for an NSSA, in seconds. When the interval
expires, an elected translator determines that its services are no longer
required.
The default value is 40 seconds.
Command mode: Router OSPF3
no area <0‐2> stability­interval
Resets the stability interval for the NSSA to its default value of 40 seconds.
Command mode: Router OSPF3
area <0‐2> translation­role {always|candidate}
Configures the translation role for an NSSA area, as follows:
always: Type 7 LSAs are always translated into Type 5 LSAs.

candidate: An NSSA border router participates in the translator election

process.
The default setting is candidate.
Command mode: Router OSPF3
no area <0‐2> translation­role
Resets the translation role for the NSSA to its default value ‐ candidate.
Command mode: Router OSPF3
area <0‐2> type {transit|stub|nssa} [no­summary]
Defines the type of area. For example, when a virtual link has to be established
with the backbone, the area type must be defined as transit.
transit allows area summary information to be exchanged between

routing devices. Any area that is not a stub area or NSSA is considered to be
transit area.
stub is an area where external routing information is not distributed.

Typically, a stub area is connected to only one other area.
nssa (Not‐So‐Stubby Area) is similar to stub area with additional

capabilities. For example, routes originating from within the NSSA can be
propagated to adjacent transit and backbone areas. External routes from
outside the Autonomous System (AS) can be advertised within the NSSA
but are not distributed into other areas.
no­summary enables the no‐summary option. When enabled, the area‐border
router neither originates nor propagates Inter‐Area‐Prefix LSAs into
stub/NSSA areas. Instead it generates a default Inter‐Area‐Prefix LSA.
The default setting is disabled.
