Table 136 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 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.
The default is transit.
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. The default value is 1.
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.
The default is none.
spf <0-255>
Sets time interval between two successive SPF (shortest path first)
calculations of the shortest path tree using the Dijkstra‘s algorithm. The
default value is 10.
enable
Enables the OSPF area.
disable
Disables the OSPF area. This is the default.
delete
Deletes the OSPF area.
