Import and Export Filters

Now that BGP is enabled and neighbors have been configured, the Import Filters can be configured under Connections > [Site Name] > Route Learning > Import Filters.

By default, no routes will be imported until Import Filters have been added, as the default filter rejects all route advertisements. Expand the Import Filters section and use the (+) icon to add a filter.

Note:

For each added filter, use any combination of the Destination, Prefix, and Next Hop fields to match desired BGP routes to learn. If these fields are left with their default value of (*), all advertised BGP routes will be imported to the Oracle. Additionally, it is important to understand the impact of the Include and Enabled checkboxes. If Include is checked, routes that match the filter will be imported. On the same filter, if Include is not checked, then routes that match the filter will not be imported. The Enabled checkbox simply enables or disables the filter entirely.

Use the (+) icon to the left of the Order column to reveal Edge specific options. Click the Service Type dropdown box to expose the available options. Depending on the Service Type chosen, various additional options will be available and are listed below.

• Export Route to Appliances: If the Export Route to Appliances checkbox is enabled, the Appliance will communicate route data to Appliances at other sites if WAN-to-WAN forwarding is enabled. This functionality is enabled by default but only applies to the following Service Types: Local and LAN GRE Tunnel.
• Eligibility Based on Gateway: If the gateway becomes unreachable, this feature will ensure that traffic is not sent to matching routes.
• Cost: The cost will be applied to the matched routes when importing into the Appliance's route table. The default Edge Cost is 6.
• Service Type: Choose a Service Type from all the existing, supported Oracle Services.
• Recursive Route: When the Service Type is Conduit, check this option to find the Conduit name from an imported route's source router automatically.
• Service Name: The name of the service that matching routes will use.
• Eligibility Based on Path: If enabled, Path state becomes criteria for filters.

Once configuration of the Edge is complete, it should be saved and the Change Management process from the NCN should be used to push the configuration changes to the APNAs.
