Command

Description

 

 

areaid <IP address>

Defines the area ID 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 nonepasswordmd5

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.
