RPKI configuration
The RPKI validation performed by BGPalerter can be configured in config.yml
in the rpki
section.
rpki:
vrpProvider: ntt
preCacheROAs: true,
refreshVrpListMinutes: 15
This configuration will be used across the entire process (e.g., by monitorRPKI
, monitorHijack
, monitorROAs
).
Below you can see the parameters available:
Parameter | Description |
---|---|
preCacheROAs | When this parameter is set to true (default), BGPalerter will download Validated ROA Payloads (VRPs) lists locally instead of using online validation. More info here. |
refreshVrpListMinutes | If preCacheROAs is set to true, this parameter allows to specify a refresh time for the VRPs lists (read here for the minimum refresh time allowed). |
vrpProvider | A string indicating the provider of the VRPs list. Possible options are: ntt (default), cloudflare , rpkiclient , ripe , external , api . The external and api options are used to specify your own VRP source, read here. |
vrpFile | A JSON file with an array of VRPs. See example below. |
markDataAsStaleAfterMinutes | The amount of minutes (integer) after which an unchanged VRP list is marked as stale. Set to 0 to disable the check. |
Use your own VRPs
Using external VRP providers for the monitoring is quick and easy, but you are essentially trusting somebody else writing the VRP file correctly.
Instead, you can specify your own VRPs in two ways:
- Using your own API producing JSON output;
- Using your favourite rpki validator to generate a file locally.
In case the download of the VRP data fails, an online provider is used (the error is reported in the logs).
Use your own API
To use your own API you need to set the following options in config.yml:
rpki:
vrpProvider: api
url: https://my-api.api.com/vrps/
preCacheROAs: true
Remember, you must specify the url when you use "api" as vrpProvider
The API must return the JSON format described here;
Use your own VRP file
You can generate your JSON VRP file periodically and BGPalerter will detect changes and reload it automatically. To do so, you have to use the following options in config.yml:
rpki:
vrpProvider: external
vrpFile: myfile.json
preCacheROAs: true
Remember, you must specify vrpFile when you use "external" as vrpProvider
The VRPs file must be in the following format:
[
{
"prefix": "123.4.5.0/22",
"asn": 1234,
"maxLength": 24
},
{
"prefix": "321.4.5.0/22",
"asn": 9876,
"maxLength": 22
}
]
Also the following format is supported:
{
roas: [ ... ] // containing items as described above
}
You can use any of the RPKI validator that support JSON as output format to generate it. Below some copy-paste examples.
