OSPF Area Index Configuration Menu options
Command Description
areaid <IP address>
Defines the area ID 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—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—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 none|password|md5
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.
