BMP

The BGP Monitoring Protocol (BMP) described in RFC 7854 defines statistics message types to observe events that occur on a monitored router. This document defines new statistics types to monitor BMP Adj-RIB-In and Adj-RIB-Out Routing Information Bases (RIBs).

RFC 7854, the BGP Monitoring Protocol (BMP), uses different message types for different purposes. Most of these are structured as Type, Length, Value (TLV). One message type, the Peer Up message, lacks a set of TLVs defined for its use, instead sharing a namespace with the Initiation message. Experience has shown that this namespace sharing was a mistake, as it hampers the extension of the protocol.

This document updates RFC 7854 by creating an independent namespace for the Peer Up message. It also updates RFCs 8671 and 9069 by moving defined codepoints into the newly introduced registry. Compliant implementations of RFCs 7854, 8671, and 9069 also comply with this specification.

This document updates RFC 7854, "BGP Monitoring Protocol (BMP)", by changing the registration procedures for several registries. Specifically, any BMP registry with a range of 32768-65530 designated "Specification Required" has that range redesignated as "First Come First Served".

The BGP Monitoring Protocol (BMP) defines access to local Routing Information Bases (RIBs). This document updates BMP (RFC 7854) by adding access to the Local Routing Information Base (Loc-RIB), as defined in RFC 4271. The Loc-RIB contains the routes that have been selected by the local BGP speaker's Decision Process.

The BGP Monitoring Protocol (BMP) only defines access to the Adj-RIB-In Routing Information Bases (RIBs). This document updates BMP (RFC 7854) by adding access to the Adj-RIB-Out RIBs. It also adds a new flag to the peer header to distinguish between Adj-RIB-In and Adj-RIB-Out.

This document defines the BGP Monitoring Protocol (BMP), which can be used to monitor BGP sessions. BMP is intended to provide a convenient interface for obtaining route views. Prior to the introduction of BMP, screen scraping was the most commonly used approach to obtaining such views. The design goals are to keep BMP simple, useful, easily implemented, and minimally service affecting. BMP is not suitable for use as a routing protocol.
