Command

Description

 

 

areaid <IP address>Defines the IP address of the OSPF area number.

 

 

type transitstubnssa

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 nonepasswordmd5Defines 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.
