Command Syntax and Usage
areaid <IP address (such as, 192.4.17.101)>
Defines the IP address 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 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 exam-
ple, 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 <metric value (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 none|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.
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.
