Expires 20 December 2026 [Page 2] Internet-Draft YANG Data Model for RTR June 2026 1. Introduction [RFC6810] and [RFC8210] describes a protocol to deliver Resource Public Key Infrastructure (RPKI) prefix origin data and router keys from a trusted cache server to a router, referred to as the RPKI to Router (RTR) protocol. [I-D.ietf-sidrops-8210bis] describes version 2 of the RTR protocol, which adds a new Autonomous System Provider Authorization (ASPA)) PDU type. This document defines YANG [RFC7950] data models for managing RTR protocol ([RFC6810], [RFC8210], and [I-D.ietf-sidrops-8210bis]). 2. Terminology and Notation Conventions 2.1. Requirements Notation The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT", "SHOULD", "SHOULD NOT", "RECOMMENDED", "NOT RECOMMENDED", "MAY", and "OPTIONAL" in this document are to be interpreted as described in BCP 14 [RFC2119] [RFC8174] when, and only when, they appear in all capitals, as shown here. 2.2. Terminology The following terms are defined in [RFC7950] and are not redefined here: * augment * data model * data node * module * namespace * YANG 2.3. Tree Diagrams Tree diagrams used in this document follow the notation defined in [RFC8340]. Liu, et al. Expires 20 December 2026 [Page 3] Internet-Draft YANG Data Model for RTR June 2026 3. Data Model Overview This document defines two YANG modules: "ietf-rpki-rtr" and "ietf- rpki-table". The "ietf-rpki-rtr" YANG module provides the methods for managing RTR protocol. It includes: * Connectivity parameters, such as RPKI cache server IP address and destination port. * Session parameters, such as purge time, refresh time, response time. * Session status and statistics, such as session ID, serial number, number of received and transmitted messages. The "ietf-rpki-table" YANG module provides the methods for managing records of RTR protocol and the corresponding state hash which is a hash value used in the Canonical Cache Representation (CCR) content [I-D.ietf-sidrops-rpki-ccr]. It includes: * Validated ROA Payload (VRP) records. * Router Key records. * ASPA records. * CCR state hash, which is optional and is used to verify the integrity and consistency of RPKI data originating from the RPKI cache. 4. RPKI to Router YANG Module 4.1. Tree View The full tree of the "ietf-rpki-rtr" YANG module is provided in Appendix A. The following subsections list the subtree structures. 4.1.1. Overall Structure The overall tree structure of the "ietf-rpki-rtr" YANG module is shown in Figure 1. The "ietf-rpki-rtr" YANG module augments the core routing YANG module "ietf-routing" specified in [RFC8349] for managing RTR protocol sessions. Specifically, this YANG module augments "/rt:routing/ rt:control-plane-protocols/rt:control-plane-protocol". Liu, et al.

Tree View The full tree of the "ietf-rpki-table" YANG module is provided in Appendix B. The following subsections list the subtree structures. 5.1.1. Overall Structure The overall tree structure of the "ietf-rpki-table" YANG module is shown in Figure 11. The "ietf-rpki-table" YANG module also augments the core routing YANG module "ietf-routing" specified in [RFC8349]. Specifically, this YANG module augments "/rt:routing". module: ietf-rpki-table augment /rt:routing: +--ro vrp-tables | +--ro vrp-table* [name] | ... +--ro router-key-tables | +--ro router-key-table* [name] | ... +--ro aspa-tables +--ro aspa-table* [name] ... Figure 11: Overall RPKI Table Tree Structure The "ietf-rpki-rtr" YANG module has three containers: 'vrp-tables', 'router-key-tables', and 'aspa-tables'. The 'vrp-tables' container lists the VRP records received from all RPKI cache servers, and each list 'vrp-table' identifies a VRP record table received from a RPKI cache server. The 'router-key-tables' container lists the Router Key records received from all RPKI cache servers, and each list 'router-key- table' identifies a Router Key record table received from a RPKI cache server. Liu, et al. Expires 20 December 2026 [Page 28] Internet-Draft YANG Data Model for RTR June 2026 The 'aspa-tables' container lists the ASPA records received from all RPKI cache servers, and each list 'aspa-table' identifies an ASPA record table received from a RPKI cache server. 5.1.2.

Implementation Status Note to the RFC Editor - remove this section before publication, as well as remove the reference to [RFC7942]. This section records the status of known implementations of the protocol defined by this specification at the time of posting of this Internet-Draft, and is based on a proposal described in [RFC7942]. The description of implementations in this section is intended to assist the IETF in its decision processes in progressing drafts to RFCs. Please note that the listing of any individual implementation here does not imply endorsement by the IETF. Furthermore, no effort has been spent to verify the information presented here that was supplied by IETF contributors. This is not intended as, and must not be construed to be, a catalog of available implementations or their features. Readers are advised to note that other implementations may exist. Liu, et al. Expires 20 December 2026 [Page 41] Internet-Draft YANG Data Model for RTR June 2026 According to [RFC7942], "this will allow reviewers and working groups to assign due consideration to documents that have the benefit of running code, which may serve as evidence of valuable experimentation and feedback that have made the implemented protocols more mature. It is up to the individual working groups to use this information as they see fit". 6.1.

Security Considerations This section is modeled after the template described in Section 3.7.1 of [RFC9907]. The "ietf-rpki-rtr" YANG module and "ietf-rpki-table" YANG module define data models that are designed to be accessed via YANG-based management protocols, such as Network Configuration Protocol (NETCONF) [RFC6241] and RESTCONF [RFC8040]. These YANG-based management protocols (1) have to use a secure transport layer (e.g., Secure Shell (SSH) [RFC4252], TLS [RFC8446], and QUIC [RFC9000]) and (2) have to use mutual authentication. The Network Configuration Access Control Model (NACM) [RFC8341] provides the means to restrict access for particular NETCONF or RESTCONF users to a preconfigured subset of all available NETCONF or RESTCONF protocol operations and content. Liu, et al. Expires 20 December 2026 [Page 43] Internet-Draft YANG Data Model for RTR June 2026 There are a number of data nodes defined in these YANG modules that are writable/creatable/deletable (i.e., config true, which is the default). All writable data nodes are likely to be sensitive or vulnerable in some network environments. Write operations (e.g., edit-config) and delete operations to these data nodes without proper protection or authentication can have a negative effect on network operations. The following subtrees and data nodes have particular sensitivities/vulnerabilities: rpki-rtr:rpki-rtr/rpki-rtr:sessions/rpki-rtr:session/rpki- rtr:server-address rpki-rtr:rpki-rtr/rpki-rtr:sessions/rpki-rtr:session/rpki- rtr:server-port rpki-rtr:rpki-rtr/rpki-rtr:sessions/rpki-rtr:session/rpki- rtr:local-address rpki-rtr:rpki-rtr/rpki-rtr:sessions/rpki-rtr:session/rpki- rtr:local-port rpki-rtr:rpki-rtr/rpki-rtr:sessions/rpki-rtr:session/rpki- rtr:enabled rpki-rtr:rpki-rtr/rpki-rtr:sessions/rpki-rtr:session/rpki- rtr:preference rpki-rtr:rpki-rtr/rpki-rtr:sessions/rpki-rtr:session/rpki- rtr:description rpki-rtr:rpki-rtr/rpki-rtr:sessions/rpki-rtr:session/rpki- rtr:enable-authentication rpki-rtr:rpki-rtr/rpki-rtr:sessions/rpki-rtr:session/rpki- rtr:authentication rpki-rtr:rpki-rtr/rpki-rtr:sessions/rpki-rtr:session/rpki- rtr:vrp-limit rpki-rtr:rpki-rtr/rpki-rtr:sessions/rpki-rtr:session/rpki- rtr:aspa-limit Some of the readable data nodes in these YANG modules may be considered sensitive or vulnerable in some network environments.
