If you are a Hurricane Electric customer you may be receiving e-mails like the following:

Dear ASXXX,

Routing Security Report for ASXXX

Hurricane Electric cares about your routing security.  We filter all BGP sessions using prefix filters based on IRR and RPKI.

This report is being sent to help you identify prefixes which may need either their IRR or RPKI information created or updated 
and to also help you identify possibly hijacked routes you may be accepting and reannouncing.  

Routes with RPKI status INVALID_ASN strongly indicate a serious problem.

IPv4 SUMMARY

Routes accepted: 3
Routes rejected: 3
Routes with RPKI status VALID: 0
Routes with RPKI status INVALID: 0

IPv6 SUMMARY

Routes accepted: 1
Routes rejected: 0
Routes with RPKI status VALID: 0
Routes with RPKI status INVALID: 0

We currently do not have a valid as-set name for your network.  Please add an export line to your aut-num ASXXXX 
that references your as-set name.  For example,

export: to AS-ANY announce your-as-set-name

If you do not currently have an as-set, we recommend you create one named ASXXXX:AS-ALL

Your as-set should contain just your ASN and your customers' ASNs and/or as-sets (not your peers or upstream providers).

What does this mean for you as a service provider? If you use Hurricane Electric as transit or peer with them on an exchange you will need to have ROAs for your blocksand have routing registry objects. I did a tutorial based upon Arin which can be found at: https://blog.j2sw.com/networking/routing-registries-and-you/

In short you need to do the following:

• Create a mntner object (equivalent of a user account) to give you the ability to create IRR objects in your selected IRR database
• Create an aut-num to represent your autonomous system and describe its contact information (admin and technical) and your routing policy
• Create an as-set to describe which autonous system numbers your peers should expect to see from you (namely your own and your transit customers)
• Create a route/route6 object for every prefix originated from your network
• Update your peeringdb profile to include your IRR peering policy
• Generate RPKI https://www.arin.net/resources/manage/rpki/roa_request/#creating-a-roa-in-arin-online

Clarification:
Some folks are confusing having valid ROAs with your router supporting RPKI with route origin validation in real-time. These two are separate things. You create ROA records with your RIR, such as ARIN, which has nothing to do with route validation on your router.

Also, HE is filtering any RPKI INVALID routes. Does this mean they are requiring RPKI? You be the judge.
