Table of Contents

1. 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 [RFC2119] [RFC8174] when, and only when, they appear in all capitals, as shown here.¶

Routing Information Bases, peers, monitoring stations are defined in [RFC7854].¶

2. Introduction

This document specifies a YANG module for configuring and monitoring the BGP Monitoring Protocol (BMP) [RFC7854]. 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.¶

3. Model summary

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.¶

5. Security Considerations

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 [RFC6241] or RESTCONF [RFC8040]. The lowest NETCONF layer is the secure transport layer, and the mandatory-to-implement secure transport is Secure Shell (SSH) [RFC6242]. The lowest RESTCONF layer is HTTPS, and the mandatory-to-implement secure transport is TLS [RFC8446].¶

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.¶
