Support for Local RIB in BGP Monitoring Protocol (BMP)
draft-ietf-grow-bmp-local-rib-07
Abstract
The BGP Monitoring Protocol (BMP) defines access to the Adj-RIB-In
and locally originated routes (e.g. routes distributed into BGP from
protocols such as static) but not access to the BGP instance Loc-RIB.
This document updates the BGP Monitoring Protocol (BMP) RFC 7854 by
adding access to the BGP instance Local-RIB, as defined in RFC 4271
the routes that have been selected by the local BGP speaker's
Decision Process. These are the routes over all peers, locally
originated, and after best-path selection.
