IETF 124 (Montreal) digest Program Adjacent pick Montreal · 1–7 November 2025

Draft Slides Session recording Materials

Paolo Lucente (NTT Data), Yunan Gu (Huawei) — GROW WG document

  • Why: BMP is how BGP is observed; Route Monitoring, Stats Reports, and Peer Down messages lack TLV extensibility, which blocks richer per-message telemetry — and the FlowSpec-feedback work below explicitly wants to export over BMP.
  • What: Updates RFC 7854 to support optional TLVs on all BMP message types, bumps the protocol version for backward compatibility, defines essential TLVs, and adds an Enterprise (E) bit allowing per-vendor type values.
  • How: WG-document mid-flight: post-E-bit-merge wording fixes pending, Stats messages need a container TLV to hold other optional TLVs, and an open question on merging draft-younsi-grow-bmp-snts.
  • Where applicable: BGP monitoring collectors and vendor telemetry stacks; broadly applicable operational plumbing rather than a research item.
