BGP Monitoring Protocol
draft-ietf-grow-bmp-14
Abstract
This document defines a protocol, BMP, that can be used to monitor
BGP sessions. BMP is intended to provide a convenient interface for
obtaining route views. Prior to 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.
