BGP Monitoring Protocol

GoBGP supports BGP Monitoring Protocol (RFC 7854), which provides a convenient interface for obtaining route views.

Prerequisites

Assume you finished Getting Started.

Contents

Configuration

Add [bmp-servers] session to enable BMP.

[global.config]
  as = 64512
  router-id = "192.168.255.1"

[[bmp-servers]]
  [bmp-servers.config]
    address = "127.0.0.1"
    port=11019

The supported route monitoring policy types are:

  • pre-policy (Default)
  • post-policy
  • both (Obsoleted)
  • local-rib
  • all

The pre-policy and post-policy types report the Adj-RIB-In of each peer, so they carry only the routes received from that peer. Routes that GoBGP originates itself, such as the ones added through the API or the CLI, injected from a VRF, or redistributed by zebra, are reported by the local-rib type instead. That is the Loc-RIB Instance Peer of RFC 9069, which replaced Section 8.2 of RFC 7854.

Enable post-policy support as follows:

[[bmp-servers]]
  [bmp-servers.config]
    address = "127.0.0.1"
    port=11019
    route-monitoring-policy = "post-policy"

Enable all policies support as follows:

[[bmp-servers]]
  [bmp-servers.config]
    address = "127.0.0.1"
    port=11019
    route-monitoring-policy = "all"

To enable BMP stats reports, specify the interval seconds to send statistics messages. The default value is 0 and no statistics messages are sent. Please note the range of this interval is 15 though 65535 seconds.

[[bmp-servers]]
  [bmp-servers.config]
    address = "127.0.0.1"
    port=11019
    statistics-timeout = 3600

To enable route mirroring feature, specify true for route-mirroring-enabled option. Please note this option is mainly for debugging purpose.

[[bmp-servers]]
  [bmp-servers.config]
    address = "127.0.0.1"
    port=11019
    route-mirroring-enabled = true

Verification

Let's check if BMP works with a bmp server. You can find some OSS BMP server implementations such as yambp, OpenBMP, etc.
