Add BGP Monitoring Protocol (BMP) support by ihebboubaker · Pull Request #1283 · openconfig/public

Add BGP Monitoring Protocol (BMP) Model

Change Scope

• This PR adds a new YANG model for BGP Monitoring Protocol (BMP) as defined in RFC 7854. The model provides configuration and operational state for BMP at global, neighbor, and peer-group levels with support for AFI-SAFI granularity.

• This change is backwards compatible as it only adds new nodes through augmentation of the existing BGP model without modifying any existing structures.

Additional Information

The BMP model includes support for:

Global BMP configuration
BMP monitoring stations with AFI-SAFI granularity
Station groups for managing multiple collectors
TCP keepalive settings
Route monitoring policy configuration
Message counters for operational state
Per-neighbor and per-peer-group BMP configuration

Is a new module proposed here (which is not a submodule) thus start the versioning at 0.1.0

This model doesn't appear to need any edits at all - no version increment is needed

Some overall comments:

You are anchoring global BMP config/state inside a BGP protocol instance within a network-instance. I would question the association to a "protocol instance" here if this is necessary and also the NI anchor point vs. NI reference as seen in other "service" definitions (e.g. dial-out similar technologies)
List keys must be a leafref to subsequent ../config/ or ../state/ nodes (e.g. stations/station/name)
Am I missing where station-groups is of use? I believe I only see a definition but no reference/use

You are defining a relative path leafref within a grouping. If the grouping is intended for reuse then it is subject to dependency hiearchies that sit at the same level anchor points

Minor nit: In most OC models, we use 'source-address' for this leaf.

I don't see examples in the referenced implementations of being able to enable/disable BMP per afi/safi. Is this really needed? We should only model OC for the features we are actually using (or have an open, active feature request to use).

dplore · 2025-04-29T16:52:41Z

+    }
+  }
+
+  grouping bmp-station-config {


I think we probably need to have some support for the BMP station to be in a different network-instance than the BGP protocol. For example, we might have BGP in the DEFAULT network instance and a BMP station in a management network instance. This could be modeled by adding a 'network-instance' leaf to this grouping.

dplore · 2025-04-29T16:56:21Z

+      }
+    }

In concept this seems ok, but is this really needed? For example, are we using this in production already? I don't see any example of this in the quoted implementation references?

as noted elsewhere, you can reuse the bmp-config grouping instead of defining an identical bmp-state grouping.

I don't see peer-group and neighbor defined in the referenced implementations. How important is this?
