• External LSDB Limit - The maximum number of AS-External-LSAs that can be stored in the database. A value of -1 implies there is no limit on the number that can be saved. The valid range of values is -1 to 2147483647. • Default Metric - Sets a default for the metric of redistributed routes.This field displays the default metric if one has already been set or blank if not configured earlier. The valid values are 1 to 16777214. Enter 0 to unconfigure. • Maximum Paths - Configure the maximum number of paths that OSPF can report to a given destination. The valid values are 1 to 4. • AutoCost Reference Bandwidth - This field configures the value that OSPF uses in calculating the default metric for an interface. OSPF calculates the link cost of each interface as Cost = (Reference Bandwidth in Mbps) / (Interface Bandwidth). For example, setting this value to 1000 Mbps would cause all 1-Gbps interfaces to have a default cost of 1000/1000 = 1. For 100 Mbps interfaces, the default cost would be 1000/100 = 10. • Default Passive Setting - Enable this setting to make all interfaces on the switch operate in passive mode passive. Configuring this field overwrites any present interface level passive mode setting. OSPF does not form adjacencies on passive interfaces, but it does advertise attached networks as stub networks. Interfaces are not passive by default. It is common to configure an OSPF interface to be passive when OSPF must advertise the subnets configured on the interface, but routers on the subnet belong to other OSPF domains, such as an OSPFv3 router at the end of a 6to4 tunnel. Default Route Advertise • Default Information Originate - Enable or Disable Default Route Advertise. • Always - Sets the router advertise 0.0.0.0/0.0.0.0 when set to True. • Metric - Specifies the metric of the default route. The valid values are 1 to 16777214. Enter 0 to unconfigure. • Metric Type - Sets the metric type of the default route. Options are External Type 1 and External Type 2. External Type 2 is the default. Modifying an OSPF Configuration 1. Open the OSPF Configuration page. 2. Change values as needed. 3. Click Apply Changes. Changes are saved, and the OSPF Interface is updated.
