/lib contains a library to create your own server and client.
/file contains the structure of a JSON export file and signing capabilities.
/cmd/gortr/gortr.go is a simple implementation that fetches a list and offers it to a router.

This software comes with no warranty.

Features of the server

Refreshes a JSON list of prefixes (from either Cloudflare or a RIPE Validator)
Prometheus metrics
Lightweight
TLS
Signature verification and expiration control

Features of the API

Protocol v0 of RFC6810
Protocol v1 of RFC8210
Event-driven API
TLS

To start developing

You need a working Go environment (1.10 or newer).

$ git clone git@github.com:cloudflare/gortr.git && cd gortr
$ go build cmd/gortr/gortr.go

Install it

$ go get github.com/cloudflare/gortr/cmd/gortr

Copy cf.pub to your local directory if you want to use Cloudflare's signed JSON file.

Create TLS certificates if you want to use the TLS feature:

$ openssl ecparam -genkey -name prime256v1 -noout -outform pem > private.pem
$ openssl req -new -x509 -key private.pem -out server.pem

If you want to sign your list of prefixes, generate an ECDSA key (similar to the first command above). Then generate the public key.

$ openssl ec -in private.pem -pubout -outform pem > public.pem

Run it

$ ./gortr -bind 127.0.0.1:8282

Make sure cf.pub is in the current directory. Or pass -verify.key=path/to/cf.pub

Data sources

Use your own validator, as long as the JSON source follows the following schema:

{
  "roas": [
    {
      "prefix": "10.0.0.0/24",
      "maxLength": 24,
      "asn": "AS65001"
    },
    ...
  ]
}

Cloudflare (list curated, signed, compressed and cached in +150 PoPs)
Third-party RIPE Validators:
- NTT
- RIPE
- LACNIC

To use a data source that do not contains signatures or validity information, pass: -verify=false -checktime=false

Configure on Juniper

Configure a session to the RTR server

louis@router> show configuration routing-options validation
group TEST-RPKI {
    session 192.168.1.100 {
        port 8282;
    }
}

Add policies to validate or invalidate prefixes

louis@router> show configuration policy-options policy-statement STATEMENT-EXAMPLE
term RPKI-TEST-VAL {
    from {
        protocol bgp;
        validation-database valid;
    }
    then {
        validation-state valid;
        next term;
    }
}
term RPKI-TEST-INV {
    from {
        protocol bgp;
        validation-database invalid;
    }
    then {
        validation-state invalid;
        reject;
    }
}

Display status of the session to the RTR server.

louis@router> show validation session 192.168.1.100 detail
