Configuration Menu 132
The following table describes the Area Index Configuration Menu options.
Table 135 OSPF Area Index Configuration Menu options
Command Description
areaid <IP address>
Defines the area ID of the OSPF area number.
type transit|stub|nssa
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 area: 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 area: 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 (NSSA) 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.
metric <1-65535>
Configures a stub area to send a numeric metric value. All routes
received via that stub area carry the configured metric to potentially
influencing routing decisions.
Metric value assigns the priority for choosing the switch for default
route. Metric type determines the method for influencing routing
decisions for external routes.
auth none|password|md5
Defines the authentication method, as follows:
None: No authentication required.
Password: Authenticates simple passwords so that only trusted
routing devices can participate.
MD5: This parameter is used when MD5 cryptographic authentication
is required.
spf <0-255>
Sets time interval between two successive SPF (shortest path first)
calculations of the shortest path tree using the Dijkstra’s algorithm.
enable
Enables the OSPF area.
disable
Disables the OSPF area.
delete
Deletes the OSPF area.
cur Displays the current OSPF configuration.
