This document proposes a YANG module for BMP (BGP Monitoring Protocol) configuration and monitoring.
A complementary RPC triggers a refresh of the session of a BMP station.
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 are defined in .
This document specifies a YANG module for configuring and
monitoring the BGP Monitoring Protocol (BMP) . The model
provides parameters for defining BMP monitoring stations, the
selection of the BGP Routing Information Bases (RIBs), provides
operational metrics and enables to reset BMP monitoring sessions.
The BMP YANG model provides the methods for managing BMP monitoring stations. It includes:
Connectivity parameters, including station IP address and destination port.
BMP session parameters, such as defining the BMP initiation message
or the interval for statistics messages.
BGP Data sources. The model requires the explicit configuration
of the RIBs and address family to send to each monitoring
station. For Adj-RIB-in and Adj-RIB-out, both post and pre policy,
the model also requires the peers from which to originate
data. In those RIBs, the value "all_peers" can be used if the
operators desires to receive data of all peers.
Per BMP station status and statistics, such as established status, number
of route-monitoring messages, number of route-mirroring messages, number
of peer-down and peer-up messages, number of initiation messages.
BMP session reset RPC action.

The YANG module specified in this document defines a schema for data
that is designed to be accessed via network management protocols such
as NETCONF or RESTCONF . The lowest NETCONF layer is the secure transport layer, and the mandatory-to-implement secure transport is Secure Shell (SSH) . The lowest RESTCONF layer is HTTPS, and the mandatory-to-implement secure transport is TLS .
BGP data is sensible for security considerations. The model described
in this document could be used to send BGP information to malicious
BMP stations. Write access to this model should therefore be
properly protected.
The session-reset action can demand considerable amount of resources
from network elements. It should thus be protected from illegal access.
This document registers two URIs in the IETF XML
registry . Following the format in
, the following registrations are
requested:
URI: urn:ietf:params:xml:ns:yang:ietf-bmp
Registrant Contact: The NETCONF WG of the IETF.
XML: N/A, the requested URI is an XML namespace.
Shall we copy the TCP tuning and security parameters from the BGP specifications?The security considerations section will have to be aligned with
