Set the Prefix(es) you want to monitor. Click on Add Prefix Filter to add a new prefix filter. You can switch off the Displayed toggle next to each prefix if you want to stop viewing data from it. However, the prefix will keep being monitored. To remove a prefix you do not want to monitor anymore, select it and click Delete.
Prefix filters accept route announcements with a given prefix, regardless of origin AS. They can be set either manually by typing them in CIDR format, or they can be automatically created in bulk by the Platform, which detects the prefixes originated by defined AS filters.
The Code BGP Platform ingests data from multiple data services around the world. The data ingested by the system needs to be filtered according to the network resources you wish to monitor. In this page you can add/delete Prefix filters for this purpose, as well as choose if the related data will be displayed or not. If a BGP update (announcement/withdrawal) carrying this prefix comes in, it will be ingested. Since configuring multiple prefix filters can soon turn into a cumbersome process, the Platform provides two ways to add such filters: one manual, and one assisted by state automation. The second one essentially checks if the system has collected any prefix state related to one or more configured ASes (AS filters), and recommends them to the user for bulk insertion. Note that this filter acts with an "OR" logic with the AS filters. Finally, note that these filters also affect what is shown in the
Looking Glass tabs; if sth is not relevant to a certain Prefix filter (and with similar logic, to an AS filter), it is not exposed to the user. Setup Prefix filters can be filtered based on
Displayed state. The corresponding columns can be hidden or shown. The (filtered) table can be exported in CSV format.
