Logging of routing events in BGP Monitoring Protocol (BMP)
draft-ietf-grow-bmp-rel-04
Abstract
The BGP Monitoring Protocol (BMP) does provision for BGP session
event logging (Peer Up, Peer Down), state synchronization (Route
Monitoring), debugging (Route Mirroring) and Statistics messages,
among the others. This document defines a new Route Event Logging
(REL) message type for BMP with the aim of covering use-cases with
affinity to alerting, reporting and on-change analysis.

1. Introduction
As NLRIs are advertised and distributed, policies are applied and, as
a result, actions are performed on them. Currently, in order to
infer the outcome of an evaluation process, a comparative analysis
needs to be performed between Route Monitoring data for two distinct
observation points of interest, for example Adj-Rib-In pre-policy and
post-policy. It would be instead more useful if a monitored router
could export event-driven data with the relevant information.
Lucente & Cardona Expires 7 March 2026 [Page 2]
Internet-Draft BMP REL September 2025
The envisioned use-cases are the most diverse and range from logging
route filtering to reporting the outcome of validation processes
taking place on the monitored router, to isolating certain subsets of
data to be validated offline, to report malformed BGP packets, to
broader closed-loop operations.
This document defines a new Route Event Logging (REL) message type
that is suitable to carry event-driven data and is extensible in
nature. While the message format is similar to the Route Mirroring
message type defined in RFC 7854 [RFC7854] and to the Route
Monitoring message type as defined in [I-D.ietf-grow-bmp-tlv], the
semantics are different.
2. Terminology
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 RFC 2119 [RFC2119] RFC 8174 [RFC8174] when, and only when, they
appear in all capitals, as shown here.
3. Route Event Logging (REL) message
In basic terms a REL message does carry Events. Each Event is
logically composed by one Event Subject and one or more Event
Attributes.
The structure of the Route Event Logging message is similar to the
Route Monitoring message defined in [I-D.ietf-grow-bmp-tlv], as such
all TLVs enclosed in the message are indexed.
The message is composed of the Per-Peer Header, one mandatory BGP
Message TLV, one mandatory Informational TLV indicating the reason of
the event and any further optional Informational TLVs to better
characterize the nature of the event. An example of the indexed TLV
structure is available in Appendix A of [I-D.ietf-grow-bmp-tlv].
One or more Event Subjects are packed as part of the BGP Update PDU.
The BGP Update PDU Section 4.3 of [RFC4271] is encoded itself as part
of the BGP Message TLV with code point 4 and index set to zero. Each
Event Subject is represented by an NLRI carried in the PDU.
The BGP Message TLV may be preceeded and/or followed by indexed
Informational TLVs that carry Event Attributes, where attributes are
bound to subjects referring to their positional index within the PDU
or via a Group TLV as described in Section 5.2.1 of
[I-D.ietf-grow-bmp-tlv]
Lucente & Cardona Expires 7 March 2026 [Page 3]
Internet-Draft BMP REL September 2025
Speaking comparatively to other existing message types, REL does not
require an initial flooding of information as per the state
synchronization nature of Route Monitoring and does not aim to
provide a non-state-compressed full-fidelity view of all messages
received as per the debugging nature of Route Mirroring.
In the context of BMP REL message, and hence in the reminder of this
document, the term Event Subject and NLRI will be used
interchangeably. Also the term Event Attribute and Informational TLV
will be used interchangeably.
The following sections will describe each component of the REL
message in more detail.
3.1. Per-Peer Header
The message does start with a BMP per-peer header as defined in RFC
7854 [RFC7854], subsequently extended by RFC 8671 [RFC8671] and RFC
9069 [RFC9069] allowing, among the other things, to timestamp an
Event and set its observation point among those defined in BMP.
Because the main purpose of the REL message is to log events at the
time of applying an action, the Peer Flags field - even if applied to
Adj-Rib-In or Adj-Rib-Out does not have the concept of pre- and post-
policy. The flags are hence defined as follows:
0 1 2 3 4 5 6 7
+-+-+-+-+-+-+-+-+
|V|A| Reserved |
+-+-+-+-+-+-+-+-+
The V flag and A flag do carry the same meaning as originally defined
by RFC 7854 [RFC7854]. The remaining bits are reserved for future
use. They MUST be transmitted as 0 and their values MUST be ignored
on receipt.
3.2. BGP Update PDU
The PDU enclosed as part of a BGP Message TLV can be either a
verbatim copy or artificial, either packed from scratch or repacked
starting from an existing BGP Update PDU to only contain the relevant
NLRIs affected by an Event (one or multiple). The Event is going to
be further described by means of Event Attributes by indexed
Informational TLVs.
The choice of describing one or multiple Event Subjects via a BGP
Update PDU is because, on one hand, this does allow to not have to
invent new encodings for NLRIs, while on the other, to support all
Lucente & Cardona Expires 7 March 2026 [Page 4]
Internet-Draft BMP REL September 2025
types and encodings already supported by BGP. The advantage being
that only minimal new code, on both the exporting and the receiving
sides, will have to be produced.
3.3. Informational TLVs
Informational TLVs in BMP are formalized by the intersection of RFC
7854 [RFC7854], [I-D.ietf-grow-bmp-tlv] and
[I-D.ietf-grow-bmp-tlv-ebit]. TLVs in a REL message are indexed.
Contrary to other BMP messages where all Informational TLVs are
entirely optional, in order for a REL message to be meaningful, it
MUST contain at least one Event Reason TLV and MAY contain other
optional attribute TLVs to further characterize the Event.
A new registry called "Route Event Logging TLVs" is defined and is
seeded with the TLVs detailed in the following sections.
3.3.1. Event Reason TLV
5 = Event Reason TLV (4 octets). Indicates the IANA-registered
reason code describing the type of the event. The following reason
codes are defined as part of the "Event Reason TLV" registry:
+========+==================+
| Value | Event Reason |
+========+==================+
| 0x0001 | Log Action |
+--------+------------------+
| 0x0002 | Policy Discard |
+--------+------------------+
| 0x0004 | Validation Fail |
+--------+------------------+
| 0x0008 | Malformed Packet |
+--------+------------------+
Table 1: IANA-Registered
Event reasons
3.3.2. Log Action TLV
6 = Log Action TLV. The length is variable. The first byte defines
the nature of the logging, depending on the code point additional
data may follow. the following code points are defined:
Lucente & Cardona Expires 7 March 2026 [Page 5]
Internet-Draft BMP REL September 2025
* 1 = Config. Prefix is being logged due to a configuration
statement. Data contains a UTF-8 string whose value can be
organized freely by an implementation and is meant to give
additional information about why the log was made.
* 2 = Route unstable. Optional data contains a 4 bytes value
representing the observed timeframe in seconds, followed by a 4
bytes value indicating the amount of times the event occurred
within the timeframe.
* 3 = Crossed Warning Bound. Prefix is over the warning threshold
of the maximum number of prefixes that can be received from a BGP
neighbor. Data contains a 4 bytes value representing the
threshold number.
* 4 = Crossed Upper Bound. Prefix is over the upper threshold of
the maximum number of prefixes that can be received from a BGP
neighbor. Data contains a 4 bytes value representing the
threshold number.
3.3.3. Policy Discard TLV
7 = Policy Discard TLV. The length is variable. The first byte of
the value field indicates how the rest is organized:
* 1 = String. The value contains a UTF-8 string whose value can be
organized freely by an implementation. For example, it may
contain the routing policy name that caused the discard; or it may
list a sequence of policies and policy nodes traversed; or, more
simply, it could be a meaningful return code.
* 2 = Structured. On the escort of Section 4 of [RFC9067] and YANG
Model for Border Gateway Protocol (BGP-4) [I-D.ietf-idr-bgp-model]
the value is organized as two consecutive null-terminated strings,
the first indicating the policy name, the second the statement
name within the policy.
3.3.4. Validation Fail TLV
8 = Validation Fail TLV. The length is set to 1 byte and the value
represents a code giving more information about the specific
validation fail. Following are the defined code points:
* Code = 1: RPKI Invalid. The prefix is being marked as RPKI
'invalid' and either has no coverage or it is unknown whether it
has coverage by a valid prefix.
Lucente & Cardona Expires 7 March 2026 [Page 6]
Internet-Draft BMP REL September 2025
* Code = 2: RPKI Invalid with covering Valid prefix. The NLRI is
being marked as RPKI 'invalid' but is covered by a Valid prefix.
3.3.5. Malformed Packet TLV
9 = Malformed Packet TLV. The length is set to 1 byte and the value
represents a code giving more information about the specific
malforming. Following are the defined code points:
* Code = 1: Errored PDU. The BGP message was found to have some
error that made it unusable, causing it to be treated-as-withdraw
RFC7606 [RFC7606].
3.4. Group TLV
The Group TLV is to form N:M relationships among NLRIs in the BGP
Update PDU and TLVs of the same Route Event Logging message. This
TLV has code point 2 and follows the definition of Group TLV in
[I-D.ietf-grow-bmp-tlv].
3.5. Stateless Parsing TLV
The Stateless Parsing TLV is to allow parsing of the BGP Update PDU
independently from a Peer Up message previously received for the same
BGP session. This TLV can be especially relevant to Route Event
Logging where the BGP Update PDU is artificial. The TLV has code
point 1 , it follows the definition of Stateless Parsing TLV in
[I-D.ietf-grow-bmp-tlv] and uses code point definitions in the
Stateless Parsing Registry.
4. Examples and use-cases
REL can be used to send real-time notifications for specific routing
events enabling rapid alerting of issues like policy discards,
validation failures, or malformed packets to operators. For example,
an operator is notified immediately when a route is discarded due to
policy, assisting quick diagnosis and policy refinement.
By logging every routing event and the corresponding reason code, REL
enables thorough audits of route changes and network behavior over
time. For example, when a route fails validation, a log entry with
the "Validation Fail" reason is stored for compliance checks and
future forensics.
Lucente & Cardona Expires 7 March 2026 [Page 7]
Internet-Draft BMP REL September 2025
REL events, especially with machine-readable reason codes, can feed
analytics engines and automated workflows to correlate events across
the network and trigger remediation. For example, analytics
dashboards continuously monitor for spikes in "Malformed Packet"
events to detect possible protocol attacks or systemic
misconfigurations.
5. Operational Considerations
Route Event Logging messages are event-driven in nature so the
general recommendation is to use them to report on specific
conditions of interest in order, for example, to facilitate data
mining or avoid differential analysis. When the objective is to
annotate every received or announced NLRI then the recommendation is
to use Route Monitoring messages with BMP Path Marking
[I-D.ietf-grow-bmp-path-marking-tlv]. As an example consider RPKI
validation status: when the objective is to report on any validations
tatus (ie. valid, invalid and unknown), BMP Path Marking should be
used; when the objective is instead to report only invalids then
Route Event Logging with Validation Fail Event Reason should be used.
There exist a definite overlap between Route Event Logging when used
to report Malformed Packet and the use-cases for Route Mirroring
where Errored PDUs may be sampled for reporting. From implementors
perspective, if one wants to implement broader event-driven
notifications and does not want to offer exact mirroring of monitored
BGP sessions without state compression it may be adviceable to prefer
implementing Route Event Logging message type over Route Mirroring.
From a collector perspective, similarly, one may want to activate
distinct BMP feeds for event logging and route collection and, also
in this case, reporting malformed packets via Route Event Logging
message type may be preferrable over Route Mirroring.
Crossed warning bound and crossed upper bound events refer to the
received route thresholds that can be configured according to
Section 6.7 of [RFC4271]. Also the stats counters part of these
events is being addressed by the Definition For New BMP Statistics
Type [I-D.ietf-grow-bmp-bgp-rib-stats] document.
6. Security Considerations
It is not believed that this document adds any additional security
considerations.
Lucente & Cardona Expires 7 March 2026 [Page 8]
Internet-Draft BMP REL September 2025
7. IANA Considerations
This document requests that IANA creates all the new registries in
the following sections under the "BGP Monitoring Protocol (BMP)
