create ospf area
Description
This command is used to create an OSPF area. OSPF allows collections of contiguous networks
and hosts to be grouped together. Such a group, together with the routers having interfaces to any
one of the included networks, is called an area.
Format
create ospf area <area_id> type [normal | [stub | nssa {translate [enable | disable]}]
{stub_summary [enable | disable] | metric <value 0-65535>}]
Parameters
<area_id>
- Enter the OSPF area ID used here.
type
- Specify the OSPF area operation type. In some Autonomous Systems, the majority of the
topological database may consist of AS external advertisements. An OSPF AS external
advertisement is usually flooded throughout the entire AS. However, OSPF allows certain
areas to be configured as "stub areas". AS external advertisements are not flooded
into/throughout stub areas; routing to AS external destinations in these areas is based on a
(per-area) default only. This reduces the topological database size, and therefore the memory
requirements, for a stub area's internal routers.
normal
- Specify that the OSPF area type will be set to normal.
stub
- Specify that the OSPF area type will be set to STUB.
nssa
- Specify that the OSPF area type will be set to NSSA.
translate
- (Optional) Specify if translation will be enabled or disabled.
enable
- Specify that the translate option will be enabled.
disable
- Specify that the translate option will be disabled.
stub_summary
- (Optional) Specify whether the summary LSA is effective for this area.
enable
- Specify that the STUB summary option will be enabled.
disable
- Specify that the STUB summary option will be disabled.
metric
- (Optional) Specify the metric (1 - 65535; 0 for auto cost) of this area.
<value 0-65535>
- Enter the metric value used here. This value must be between 0 and
65535.
Restrictions
Only Administrator, Operator and Power-User level users can issue this command.
