This document defines a YANG data model for the configuration and monitoring of the BGP Monitoring Protocol (BMP).
The BGP Monitoring Protocol (BMP) provides a mechanism for
monitoring BGP sessions. This document defines a YANG data
model for BMP, specified in two YANG modules, enabling
operators to configure and manage BMP sessions; control the
data exported to monitoring stations; and collect statistics
for each BMP session. The data model is designed to
accommodate both simple and advanced deployment scenarios,
supporting granular control over network instances, RIBs,
address families, and peers.
The data model defined in this document supports the base
BMP protocol defined in . It also
supports the Loc-RIB extension defined in , allowing configuration and
monitoring of BMP reporting for routes selected into the
local BGP speaker's Loc-RIB.
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
when, and only when, they appear in all capitals, as shown here.
Routing Information Bases, peers, monitoring stations, and
initiation messages are defined in .
This document specifies two YANG modules. The main module, ietf-bmp, configures and
monitors the BGP Monitoring Protocol (BMP) on the monitored router.
A second auxiliary module, ietf-bmp-tcp-dependencies, provides extensions for configuring the TCP configuration
to BMP monitoring stations if the monitored router YANG server supports the groupings from .
The main module provides parameters for configuring the session to BMP monitoring
stations; configuration of BMP messages; provides operational
metrics and enables resetting of BMP monitoring sessions.
The ietf-bmp module imports common IETF YANG definitions for Internet
types, access control, interfaces, network instances, and routing
policy. The ietf-bmp-tcp-dependencies module imports TCP and
key-chain definitions used for TCP transport and authentication
configuration.The main module is included in . The full tree diagram
is available in . This
section provides details and examples of each part of the main module.
The secondary TCP extension module augments the definition of TCP configuration
for a monitoring station, and it is explained in .The ietf-bmp YANG module is placed at the root of the YANG tree. At its
upper level, the module lists each monitoring station. Every
monitoring station is identified by an ID, which is a string
provided by the operator. shows

]]>The rest of the subsections describe each of the containers use to configure each monitoring-station. BMP allows for active and passive
connections between the router and the BMP monitoring station as described in . In
an active connection, the router establishes the TCP connection to
the monitoring station, while in a passive one, it is the monitoring
station which initiates the connection. The ietf-bmp module
provides options for both types of connection using a choice.The following subsections describe each type of connection option, with
examples of their configuration.For an active connection, the IP address and port of the monitoring
station, together with the local endpoint must be provided. The local
endpoint can be a local IP address or a source interface. One can
optionally provide the local port for establishing the connection.
If the monitoring station is connected over a network-instance
instead of the global one, this one must also be specified. An
example of configuration is included in .Active connection example1192.0.2.157992192.0.2.2

monitoring station is provided, it must match the incoming
connection. If the monitoring station is connected through a
network-instance instead of the global one, this one must also be
specified.An incoming connection not matching a valid entry MUST be ignored by
the router. includes an example of

Initial-delay: a value in seconds that the monitored router must wait before starting the connection to the station. An operator can use this delay to let BGP converge before starting the BMP session.
Backoff time: Configuration of the backoff time strategy after failing to connect to the monitoring station. The module includes a basic exponential backoff with a default initial backoff of 30 seconds and a maximum of 720 seconds, as suggested in .

]]>The following requirements guided the design of this part of the ietf-bmp module:
Operators might not want to receive all routes from all RIBs in a network device. For instance, some devices contain a considerable amount of data that might overwhelm the monitoring station. In these cases, operators might want to only collect information from an arbitrary subset of RIBs, address families, peers.
Operators might want to configure the route monitoring messages for different network instances differently. For example, they might want to receive different address families from the global network instance than in L3 VPN network instances.
In contrast to the previous points, some operators might want a simple configuration that covers multiple cases (e.g. same config for all peers, or same config for all network instances). This would not only make configurations look smaller and concise, but will reduce the need for reconfiguring devices when you add a new peer or add a new network instance (which happens frequently on some type of networks).
Based on the previous points, the ietf-bmp module is designed to flexibly control the data sent through the BMP route monitoring packets, yet it provides options to facilitate configurations for simple cases, such as when the operator wants to receive all routes from a RIB.The route monitoring configuration is divided in a four-part hierarchy:
Network Instance
RIB Type (e.g. Adj-RIB-IN pre/post, local RIB)
Address Family
Peers
Absence of the route monitoring container will disable the route monitoring messages to the monitoring station.This section introduces these hierarchies before describing them in detail.The number of RIB types (e.g. Adj-RIB-IN/OUT, local RIB, etc) and Address families is low, and their configuration should not change frequently. Therefore, they are configured explicitly in the model. That is, the model does not provide a way of providing a default configuration for these or configuring them in groups.On the other hand, Network instances and peers require greater flexibility.For network instances, the module should configure not only the "global" network instance, but also other network instances. Also, network instances can change frequently in networks with customer connecting to Virtual Private Networks. To not force operators to change configuration at every change, the module provides methods for defining a "default" configuration for network instances. However, to provide control over the configuration, each network instance can be configured independently, if needed.A similar situation applies to peers for the Adj-RIB-IN and Adj-RIB-OUT RIBs. The module includes a way of configuring a default for all peers for simple cases, but one can provide configuration for type of peers, peergroups, or each peer individually. The next list summarizes the requirements stated in the previous two paragraphs:For network instances:
The configuration should be simple for cases where only the "global" routing instance is enabled.
The module should provide ways of configuring all Network instances (kind of a default config for any Network instance that is configured in the device).
The module should provide a way of configuring network instances individually.
For peers:
The module should provide ways of configuring all peers, kind of a default. This would be the most common case.
The module should provide ways of configuring peergroups.
The module should provide ways of configuring type of peers. For instance, only send routes from eBGP peers.
The module should provide ways of configuring individual peers. For instance, an operator might apply a route-policy to filter certain prefixes for a specific peer, or disable route monitoring messages for a peer that is noisy yet not important.
To further control the route monitoring data, the peer container includes a route-policy option in which the operator can further filter the data send to the BMP monitoring station.Each of the four hierarchies is described in the following sections.The route monitoring configuration starts with the configuration of network instances. A network instance can be configured individually, or it can be configured if it matches any of the selectors from the "bmp-ni-types" identity. Each option is explained next.The ietf-bmp module currently defines three bmp-ni-types identities: "all-ni" which selects all network instances, "non-global-ni" which selects all network instances except the global one, and "global-ni", which configures the global network instance when the device does not offer an explicit name for it. The former can be used as a "default" configuration for simple cases.Network-instances are configured under the container "bmp-data/route-monitoring/network-instance-configuration/network-instances/network-instance".An empty configuration disables route monitoring messages for the selected network-instances. Operators can also use the "enabled" leaf to disable explicitly the routing messages for the network instance. The route-monitoring data for a network instance can be configured by at most one element under the network-instance-configuration container. There SHOULD be clear rules for which element to apply to a network instance in case multiple elements can select it. The next part of the section provides rules and examples.The rules for selecting which element configures a network instance are presented next. Each point is evaluated only if the previous points do not hold.
If the name of the network instance is referenced in "network-instance-configuration/network-instances/network-instance", the network instance SHOULD be configured using this element.
If the selector 'global-ni' under the "network-instance-configuration/network-instance-selectors" exist, the global network instance SHOULD be configured using this element. Note that if a vendor has a name for the global network instance, the previous step (i.e, network instance name) will take priority over using the global-ni selector.
If the selector 'non-global-ni' under the "network-instance-configuration/network-instance-selectors" exist, any non-global network instance should be configured using its content.
Any Network Instance not referenced by any rule above SHOULD be configured using the all-ni if one exists. If it does not exist, then the network instance is not configured (and therefore no route monitoring messages from the network instance are sent to the monitoring station).
Any extension of the bmp-ni-types SHOULD provide explanations of how to deal with case in which multiple elements select the same network instance. The following section provides examples of configuring the network instance level. For now, the discussion focuses on configuration using the BMP container. To focus on the network instance configuration, the configuration under each instance is masked using "Configuration X".Examples of configuring the network instance level for Route Monitoring.monitoring_station_one192.0.2.157992192.0.2.2

]]>The example in shows a "simple" configuration. In this case, all network instances would get "Configuration D". Note that `all-ni` would also cover the global instance.Another simple configuration would just involve configuring the global network instance. In this case, information of non-global network instances would not be sent to the monitoring station. This is depicted in Example of configuring only the global network instance.monitoring_station_one192.0.2.157992192.0.2.2

]]>Each RIB type is configured explicitly in the module through a container. The ietf-bmp module currently provides containers for adj-rib-out-pre, adj-rib-out-post, adj-rib-in-post, adj-rib-in-pre and local-rib. An empty configuration or absence of a RIB-type container disables route-messages for it. Operators can also disable the route monitoring messages for each RIB explicitly by marking the "enabled" leaf as False. The next section provides an example of this, together with the address family configurations.Address families are configured explicitly within each RIB type using a list. The key is of type `afi-safi-type` without any further constraint.An empty configuration or absence of an address family disables route-messages for it. Operators can also disable the address-family route monitoring messages by marking the "enabled" leaf as False.The next examples show different ways of configuring RIB-Types and Address families. As in the previous sections, the example masks further configurations of address families with "Configuration X" to focus on the covered parts.Example of configuring RIBs and address families.monitoring_station_one192.0.2.157992192.0.2.2

]]>Example expands the examples of previous sections with RIB-Type and address families configurations. The expected result of the previous configuration would be:
For the global network instance, adj-rib-in-pre and adj-rib-in-post RIBs are enabled. In each of them IPv4 and IPv6 address families are configured. The configuration can be the same or not, depending on the requirements of the operators. Any other RIB and address families are disabled.
Network instance "network-instance-one" is disabled, meaning that route monitoring messages are disabled for that network instance.
Network instance "network-instance-two" has adj-rib-out-post enabled, but only address family ipv4-unicast is configured. The ipv6-unicast will not be configured for this instance.
For all other network instances, adj-rib-in-pre with IPv4 and IPv6 address families are configured, thanks to the configuration of all-ni
If an operator only wants to configure the IPv4/IPv6 of adj-rib-in-pre for the global instance, the configuration in plus the peer configuration (coming in next section) will be enough. Note again that even if the configuration of both address families is the same, they must be explicitly configured for each of them.Example of configuring RIBs and address families.monitoring_station_one192.0.2.157992192.0.2.2
global-niipv6-unicastipv4-unicast
]]>For adj-RIB-in and adj-RIB-out, both pre and post, the ietf-bmp module requires the selection of peer RIBs that will be transmitted to the monitoring station. The local-rib does not include this container.Peers can be configured using different "selectors", which can be one of the following:
An individual peer, using a remote address. For the configuration under the "/bmp" tree, the module does not check if the remote address exists, that would be a responsibility of the device.
Peergroups.
A group of peers matching a BGP type. i.e. eBGP peers.
One or more peers defined by a `bmp-peer-selectors` identity. The ietf-bmp module currently provides the `all-peers` identity, which selects all peers. For simple cases, this is the value that would normally be considered.
Peers MUST be selected (configured) by at most a single instance of the peers list. For the included keys in the "ietf-bmp" model, the process to select which instance to use is as follows:
If there is a peer address matching the peer, it SHOULD be configured using that instance.
If the peer matches a peergroup, it SHOULD be configured using the peer-group configuration.
If the peer is of any BGP type listed in the peer list, it SHOULD be configured using this instance.
If there is a peer instance identified with the `all-peers`, it SHOULD be configured using this instance.
Finally, if no instance covers the peer, route monitoring messages from this peer SHOULD NOT be transmitted to the monitoring station.
An empty configuration of a peer type disables route-messages for it. Operators can also disable the address-family route monitoring messages by marking the "enabled" leaf as False.Note that if an operator only wants the information of a few peers, it can enable them individually using their id. If no other configuration exists, only the messages from those enabled peers will be transmitted to the monitoring station.Any additional peer-types identity created SHOULD describe how to unambiguously select a peer when there are conflicting options (multiple options covering the peer). provides examples of the peers configuration.The local RIB, and the peer containers within the rest of rib types, include a filter container. This container includes mechanisms to filter route-monitoring messages for the specific RIB.The policy-filter can include a routing policy that, if existing, is applied to the outgoing updates to the monitoring station, and would serve as a granular way of filtering the messages that the monitoring station receives. Note that the policy-filter contains an `accept-route` default export policy. An operator can change it to a reject-route, if required.The policies created with the routing-policy can perform a large variety of actions on routes, and can filter them based on multiple characteristics. For the consistency of the data in the monitoring station, the routing policies actions MUST be restricted to accepting or rejecting routes. Furthermore, the conditions SHOULD only match prefix sets.In the example configuration from , address families IPv6 and IPv4 are configured to send all peers from the global network instance. This is an example of a simple configurationEnabling Route monitoring for all peers in the global network instance; IPv4/IPv6 Address families, in the adj-rib-in-pre RIB.monitoring_station_one192.0.2.157992192.0.2.2

]]>The ietf-bmp module provides actions to reset BMP sessions and counters.
shows the structure of the actions container.Structure of the actions containerThe "session-reset" action resets a session with a monitoring station.
The "session-counter-reset" action resets the counters in the session-stats container.To facilitate implementation, the specification is divided into two
distinct parts. The core module (ietf-bmp) is designed to configure
BMP without deep dependencies to other modules. This
is an attempt to facilitate the implementation by vendors.Additionally, a supplementary module,
ietf-bmp-tcp-dependencies,
enhances the data model's functionality but relies on the IETF TCP
YANG modules. This module can be adopted by implementations that
support the dependency.BMP is a monitoring protocol and is not a routing protocol
. A network instance
provides an instance of control-plane and forwarding functions, and
mounts the configuration of routing
protocols, such as OSPF, within it. The ietf-bmp module therefore
does not place BMP configuration under a network instance. A BMP
instance relates to a single BGP instance, and a router with
several BGP instances is expected to run one BMP instance per BGP
instance . For that reason, the module
selects the network instances to monitor explicitly, under the
"network-instance-configuration" container used for Route
Monitoring.An implementation could nevertheless place the BMP configuration
under a network-instance context. In that case, the enclosing
network instance would identify the network instance to which the
Route Monitoring configuration applies. The implementation could
then restrict an explicit network-instance selection to the
enclosing network instance, or map the configuration so that
selecting the network instance again is not required. allows an implementation to restrict
parent-referenced information to a specific instance in a similar
way. In either case, the Route Monitoring configuration of a
network instance SHOULD be defined in a single place, and the
implementation SHOULD NOT accept conflicting configurations for the
same network instance in both places.The ietf-bmp module imports ietf-yang-types and ietf-inet-types from
, ietf-netconf-acm from ,
ietf-interfaces from , ietf-network-instance from
, and ietf-routing-policy from
. The module semantics rely on the BGP
specifications in , ,
and , on the BMP specifications in
, , and
, and, for the TCP options, on

]]>Note to the RFC-Editor: Please remove this section before publishing.Arrcus implemented the entire YANG module, except the optional tcp: statements from RFC9648,
which appear in version 8.This section is modeled after the template described in Section
3.7.1 of . The ietf-bmp YANG module defines a data model that is designed to be
accessed via YANG-based management protocols, such as NETCONF
and RESTCONF . These YANG-based management
protocols (1) have to use a secure transport layer (e.g., Secure
Shell (SSH) , TLS ,
and QUIC ) and (2) have to use mutual
authentication.
The Network Configuration Access Control Model (NACM)
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.
There are a number of data nodes defined in this YANG module 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.
In particular, unauthorized
changes to the "connection" subtree of a monitoring station could
redirect or disrupt BMP export, while changes to the
"route-monitoring" subtree can alter the routing information
exposed to collectors.
Some of the readable data nodes in this YANG module may be
considered sensitive or vulnerable in some network environments. It
is thus important to control read access (e.g., via get,
get-config, or notification) to these data nodes.
There are no particularly sensitive readable data nodes.
Some of the RPC or action operations in this YANG module may be
considered sensitive or vulnerable in some network environments. It
is thus important to control access to these operations.
Specifically, the following operations have particular
sensitivities/ vulnerabilities:
The session-reset action can demand a considerable amount of resources
from network elements.
The session-counter-reset action can reset BMP session counters,
which can affect operational visibility and troubleshooting.
These actions SHOULD thus be protected from unauthorized access.

operations (e.g., edit-config) and delete operations to these data
nodes without proper protection or authentication can have a

In particular, the secure-session, ao-keychain, and md5-keychain
configuration can disable or alter BMP session authentication if
changed without proper authorization.

considered sensitive or vulnerable in some network environments. It
is thus important to control read access (e.g., via get,

There are no particularly sensitive readable data nodes.
This YANG module uses groupings from other YANG modules that
define nodes that may be considered sensitive or vulnerable in
network environments. Refer to the Security Considerations of
, , and
for information as to which nodes may be
considered sensitive or vulnerable in network environments.
IANA is requested to register the following URIs in the "ns"
registry within the "IETF XML Registry" group :IANA is requested to register the following YANG modules in the "YANG

]]>This section shows some examples of BMP configuration using the
data model.In this example, the device connects to a monitoring station
using an active connection.
The devices sends route monitoring messages for the global
instance, the adj-rib-in-pre RIB, the IPv4/IPv6 address family,
and external peers.

]]>In the next example, the device connects to a monitoring station
using a passive connection, over the network-instance monitoring.
The configuration of route monitoring messages is more complex than
in the previous example. It shows how to combine the configuration
of general identities of network instances and peers (e.g.
all-ni for NI, external for peers), and individual
configurations to support a more complex requirement. This is what
the example expects to configure:
For the global network instance, the device sends updates for
adj-rib-in-pre, address families IPv4 and IPv6. It sends updates
for all external peers except peer 198.51.100.11, which is
disabled.
Network instance monitoring is disabled for route monitoring
messages.
For the rest of network instances, route monitoring messages
are enabled from adj-rib-in-pre, address families IPv4/IPv6, and
for all peers.
