Metric Type: Metric: Set the OSPF metric type of the default route. Two types are supported: External Type 1 and External Type 2. The default value is External Type 2. Specify the metric of the default route. The valid value ranges from 1 to 16777214 and the default is 1. Area Table Process: Select: Area ID: Area Description: Area Type: Authentication Type: Summary: Redistribution: Default Cost: Default Route Advertise: Metric Type: Select one OSPF Process to display its area list. Select the desired item for configuration. It is multi-optional. Displays the configured area. Displays the description of the area and it can be modified. Displays the type of the area and it can be modified. Displays the authentication type of the area and it can be modified. Displays the Summary parameter and it can be modified. Displays the Redistribution parameter and it can be modified. Displays the stub cost of the area and it can be modified. Displays the Default Route Advertise status and it can be modified. Displays the type of default route and it can be modified. Metric: SPF runs: ABR Count: Area LSA Count: Area LSA Checksum: Displays the metric of default route and it can be modified. Displays the number of times that the intra-area route table has been calculated using this area's link-state database. This is typically done using Dijkstra's algorithm. Displays the total number of area border routers reachable within this area. This is initially zero, and is calculated in each SPF Pass. Displays the total number of link-state advertisements in this area's link-state database, excluding AS-External LSAs. Displays the 32-bit unsigned sum of the link-state advertisements' LS checksums contained in this area's link-state database. This sum excludes external (LS type 5) link-state advertisements. The sum can be used to determine if there has been a change in a router's link state database, and to compare the link-state databases of two routers. 10.9.6 Area Aggregation You can configure address ranges for an area on this page. The address range is used to consolidate or summarize routes for an area at an area boundary. The result is that a single summary route is advertised to other areas by the ABR. Routing information is condensed at area boundaries, a single route is advertised for each address range. 202
