Configuration Commands

OSFP Area Index configuration

The following table describes the Area Index Configuration commands.

Table 132 OSPF Area Index Configuration commands

Command

Description

 

 

area <0-2> area-id <A.B.C.D>

Defines the area ID of the OSPF area number.

 

Command mode: Router OSPF

 

 

area <0-2> type

Defines the type of area. For example, when a virtual link has to be

{transitstubnssa}

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.

 

Command mode: Router OSPF

 

 

area <0-2> stub-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.

 

Command mode: Router OSPF

 

 

[no] area <0-2> authentication-

Defines the authentication method, as follows:

type {passwordmd5}

no—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.

 

Command mode: Router OSPF

 

 

area <0-2> spf-interval <0-255>

Sets time interval between two successive SPF (shortest path first)

 

calculations of the shortest path tree using the Dijkstra’s algorithm.

 

Command mode: Router OSPF

 

 

area <0-2> enable

Enables the OSPF area.

 

Command mode: Router OSPF

 

 

no area <0-2> enable

Disables the OSPF area.

 

Command mode: Router OSPF

 

 

no area <0-2>

Deletes the OSPF area.

 

Command mode: Router OSPF
