Table 148 OSPF Area Index Configuration Menu options
Command Description
areaid <IP address> 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 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.
