Command Syntax and Usage
area <0-2> area-id <IP address>
Defines the IP address of the OSPF area number.
Command mode: Router OSPF
area <0-2> 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.
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-type {password|md5}
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.
Command mode: Router OSPF
