xStack® DGS-3620 Series Layer 3 Managed Stackable Gigabit Switch CLI Reference Guide DGS-3620-28SC:admin#show ospf aggregation Command: show ospf aggregation OSPF Area Aggregation Settings Area ID Aggregated LSDB Advertise Network Address Type 0.0.0.0 10.90.0.0/16 Summary Enabled 0.0.0.0 10.90.0.0/17 Summary Enabled 0.0.0.0 10.90.64.0/18 Summary Enabled Total Entries : 3 DGS-3620-28SC:admin# 69-6 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 type [normal | [stub | nssa {translate [enable | disable]}] {stub_summary [enable | disable] | metric }] Parameters - Enter the OSPF area ID used here. type - Specifies 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 - Specifies that the OSPF area type will be set to normal. stub - Specifies that the OSPF area type will be set to STUB. nssa - Specifies that the OSPF area type will be set to NSSA. translate - (Optional) Specifies whether translation will be enabled or disabled. enable - Specifies that the translate option will be enabled. disable - Specifies that the translate option will be disabled. stub_summary - (Optional) Specifies whether the summary LSA is effective for this area. enable - Specifies that the STUB summary option will be enabled. disable - Specifies that the STUB summary option will be disabled. metric - (Optional) Specifies the metric (1 - 65535; 0 for auto cost) of this area. - Enter the metric value used here. This value must be between 0 and 65535. 757
