1. Introduction
Nowadays network operators are using BGP Monitoring Protocol (BMP)
[RFC7854] to monitor the BGP peerings and RIB's. With
[I-D.ietf-nmop-message-broker-telemetry-message] a machine and human
readable extensible Network Telemetry message schema in YANG
[RFC7950] has been defined.
Network operators organize their data in a Data Mesh [Deh22] where a
Message Broker such as Apache Kafka [Kaf11] or Apache Pulsar [Pul16]
facilitates the exchange of messages among data processing
components.
With YANG Message Keys for Message Broker Integration
[I-D.netana-nmop-yang-message-broker-message-key] how Dimensional
YANG data can be indexed and addressed in Message Brokers are being
described.

Internet-Draft BMP YANG Network Telemetry Message February 2026
This document describes how
[I-D.ietf-nmop-message-broker-telemetry-message] defined Network
Telemetry message is being extended to support BMP data
transformation to YANG at the Network Telemetry data collector and
being indexed and addressed in Message Broker based on
[I-D.netana-nmop-yang-message-broker-message-key] principles at the
YANG Message Broker Producer.
2. Conventions and Definitions
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

* Topic: A communication channel for publishing and subscribing
messages with one or more subjects and partitions.
* Topic Compaction: The act of compressing messages in a topic to
the latest state. As used with Apache Pulsar. Apache Kafka uses
the term Log Compaction with identical meaning.
* Partition: Messages in a topic are spread over hash buckets where
a hash bucket refers to a partition being stored on one message
broker node. Message ordering is guaranteed within a partition.
* Message: A piece of structured data sent between data processing
components to facilitate communication in a distributed system
* Message Key: Metadata associated with a message to facilitate
deterministic hash bucketing.
The following terms are used as defined in [RFC7854]:
* BMP
* BMP Message
* Adj-RIB-In
* Pre-policy Adj-RIB-In
* Post-Policy Adj-RIB-In
The following terms are used as defined in [RFC8671]:
* Adj-RIB-Out
* Pre-policy Adj-RIB-Out
* Post-policy Adj-RIB-Out
The following terms are used as defined in [RFC9069]:

* Loc-RIB
This document defines the following term:
* BMP Index: A unique identifier created depending on BMP Message
Type from multiple BMP and BGP data dimensions. The BMP Index is
used to generate the Message Key. See Section 5.1.

3. Relationship to other documents
text
3.1. Relationship to draft-ietf-nmop-message-broker-telemetry-message
[I-D.ietf-nmop-message-broker-telemetry-message] defines with 'ietf-
telemetry-message' YANG module a base Network Telemetry Message
schema being used between Section 4.6 of Message Broker Producer
[I-D.ietf-nmop-yang-message-broker-integration] and Section 4.7 of
Message Broker Consumer
[I-D.ietf-nmop-yang-message-broker-integration] and with 'ietf-yang-
push-telemetry-message' YANG module an extension that supports YANG-
Push specific subscription metadata.
This document defines one BMP YANG module Figure 2, and 3 BGP RIB
submodules Section 4.1 which are being used in the anydata "payload"
[I-D.ietf-nmop-message-broker-telemetry-message] defined in 'ietf-
telemetry-message' YANG module.
3.2. Relationship to draft-ietf-idr-bgp-model
[I-D.ietf-idr-bgp-model] defines with 'ietf-bgp' a YANG module and
with 'iana-bgp-community-types', 'iana-bgp-notification', 'iana-bgp-
rib-types', 'iana-bgp-types', 'ietf-bgp-capabilities', 'ietf-bgp-
common', 'ietf-bgp-common-multiprotocol', 'ietf-bgp-common-
structure', 'ietf-bgp-neighbor', 'ietf-bgp-policy', 'ietf-bgp-rib',
'ietf-bgp-rib-attributes' and 'ietf-bgp-rib-tables' submodules.
This document is using the content of the 'rib' YANG grouping defined
in 'ietf-bgp-rib' submodule and renames the YANG grouping to 'rib-
entry' and restructures the data taxonomy to allow a single BGP RIB
entry to be serialized in a Telemetry Message on Message Broker in
the 'ietf-bmp-bgp-rib-entry' submodule. The 'clear-routes' YANG
grouping used in the 'rib' YANG grouping has been removed since a
Telemetry Message only covers operational metrics.
Since 'ietf-bgp-rib' uses groupings from 'ietf-bgp-rib-attributes'
and 'ietf-bgp-rib-tables' and both 'ietf-bgp-rib-attributes' and
'ietf-bgp-rib-tables'YANG submodules Section 7.2.2 of belongs to
[RFC7950] 'ietf-bgp' main module, the YANG submodules have been
renamed to 'ietf-bmp-bgp-rib-attributes' and ietf-bmp-bgp-rib-
tables'.
If 'ietf-bgp-rib-attributes' and 'ietf-bgp-rib-tables' would not be
'ietf-bgp' submodules, they could be reused as is with 'ietf-bmp-bgp-
rib-entry'. Since this would imply than a normative document
dependency a reasonable timeline needs to be coordinated. Once these

Internet-Draft BMP YANG Network Telemetry Message February 2026
clarifications have been concluded this section remains. The
[I-D.ietf-idr-bgp-model] authors are being honored under
Appendix "Contributors" for their contribution on the BGP YANG
modelling this document uses.
3.3. Relationship to draft-ietf-grow-bmp-yang
[I-D.ietf-grow-bmp-yang] defines with 'ietf-bmp' YANG module the
configuration and monitoring of BMP. While there is no direct
relationship between this document and its defined YANG modules, it
is worth mentioning that the with [I-D.ietf-grow-bmp-yang] subscribed
BMP data is being transformed at BMP monitoring stations to Message
Brokers as described in this document.
4. BMP YANG Modules
The BMP YANG module for Network Telemetry messages defines the BMP
subscription metadata and depending on BMP Message type different
metadata structures.
Where the 3 BGP RIB YANG submodules extend the BMP YANG module with
BGP RIB structures for BMP route-monitoring and route-mirroring
Message types.
