What is ROA?

A Route Origination Authorization details which AS is authorised to advertise which originating IP prefixes. A ROA may also include prefix length information.

What is RPKI?

Resource Public Key Infrastructure is basically a framework for securing the routing infrastructure.
It provides a way to connect number resource information to a trust anchor.

What is RTR?

The Resource Public Key Infrastructure (RPKI) to Router Protocol provides a way for a router to access RPKI validation information.
It provides the router with validity information regarding prefix origination:

    The route announcement is covered by a ROA and the announcing AS is validated
    The route announcement is covered by a ROA and the announcing AS is invalid (possibly hijacking)
    There exists no ROA for the route announcement

How can I implement ROA on dn42?

On dn42 we generate ROA information from the dn42 registry.
ROA json/bird files can be generated using dn42regsrv. It is also possible to integrate this with a RTR cache server such as gortr.


You can find a hosted example of dn42regsrv at https://explorer.burble.com/

Instructions on how to host dn42regsrv yourself can be found on the git repo of dn42regsrv.

You can also run dn42regsrv via docker (then available at

git checkout https://git.burble.com/burble.dn42/dn42regsrv.git .
cd contrib/docker
docker-compose up -d

Documentation for the api endpoints can be found here: https://git.burble.com/burble.dn42/dn42regsrv/src/master/API.md


burble kindly provides ready-to-use files for gortr here:


You can use these to simply run gortr via docker:

docker run -ti -p 8082:8082 cloudflare/gortr -cache https://dn42.burble.com/roa/dn42_roa_46.json -verify=false -checktime=false -bind :8082


rtrtr is a RTR server from NLNet Labs. It's compatible with the dn42regsrv ROA-JSON or burbles provided one (https://dn42.burble.com/roa/dn42_roa_46.json) too.

NLNet Labs provides an official docker image. You just have to bind mount a suitable configuration file:

docker run -d -v /etc/rtrtr.conf:/etc/rtrtr.conf -p 323:323/tcp nlnetlabs/rtrtr -c /etc/rtrtr.conf

This is a working configuration file for dn42. Maybe change the listen addresses:

log_level = "debug"
log_target = "stderr"
http-listen = []
type = "json"
uri = "https://dn42.burble.com/roa/dn42_roa_46.json"
refresh = 600
type = "rtr"
listen = ["", "[::]:323"]
unit = "dn42-json"

For more information cosult the official documentation: https://rtrtr.docs.nlnetlabs.nl/en/stable/

Other tools / generators

This is all to complicated, is there an easy all-in-one package for RTR?

TODO: Publish docker-compose-yml to git for gortr+dn42regsrv

How do I integrate RTR with my BGP implementation

You have to consult the documentation of your implementation for that. We will provide configuration examples on the specific pages.
