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:
- VALID
The route announcement is covered by a ROA and the announcing AS is validated - INVALID
The route announcement is covered by a ROA and the announcing AS is invalid (possibly hijacking) - UNKNOWN
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.
dn42regsrv
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 127.0.0.1:8042):
git checkout https://git.dn42.us/burble/dn42regsrv.git .
cd contrib/docker
./build.sh
docker-compose up -d
Documentation for the api endpoints can be found here: https://git.dn42.us/burble/dn42regsrv/src/master/API.md
gortr
burble kindly provides ready-to-use files for gortr here:
https://dn42.burble.com/roa/dn42_roa_46.json
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
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.
