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: 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 (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.
The default is transit.
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. The default value is 1.
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.
The default is none.
spf <0-255>
Sets time interval between two successive SPF (shortest path first)
calculations of the shortest path tree using the Dijkstra‘s algorithm. The
default value is 10.
enable
Enables the OSPF area.
disable
Disables the OSPF area. This is the default.
delete
Deletes the OSPF area.
cur
Displays the current OSPF configuration.
