Discussion: Draft on RPKI Trust Anchor Constraints in SIDROPS

[Sofia Silva Berenguer via NANOG <nanog () lists nanog org>]

(Apologies for duplication)

Hello all,

The NRO RPKI Program [1] has published a blog post explaining the proposed solution to concerns with the current RPKI 
Trust Anchor configuration, now documented in the Internet-Draft 
https://www.ietf.org/archive/id/draft-nro-sidrops-ta-constraints-00.txt

The draft defines a mechanism that allows RPKI Trust Anchors (TAs) to declare which TA is authoritative for which 
Internet Number Resources, helping prevent RPKI validation conflicts.

You can read the blog post here: https://www.arin.net/blog/2025/10/29/nro-rpki-program-series-6/

We welcome feedback and discussion on the sidrops mailing list [2] and during the upcoming SIDROPS WG session at IETF 
124 (Montreal, Nov 3) [3].

Warm regards,

Sofía
