Summary

This meeting of the global routing operations working group at IETF 119 covered a range of topics related to routing operations and monitoring. Presentations were given on a peering API proposal, updates to BMP-related drafts (TLV, EBIT, REL), BGP operational security best practices, and BMP statistics and reporting. A request for working group adoption of a TCP AO specification for BMP was also made.

Key Discussion Points

Peering API:
- Presentation on a new API for programmatic handling of peering requests to automate inter-AS interconnection.
- Discussion on security considerations, authorization mechanisms, and future work on PNI connections and maintenance notifications.
- The need for a state machine to manage the provisioning workflow and expectations.
BMP TLV, EBIT, and REL Drafts:
- Updates on the TLV draft to reduce parsing complexity and improve group TLV indexing.
- Discussion on the EBIT draft and the need for coordinated updates with the TLV draft.
- Debate regarding overlapping functionality between root mirroring and root event logging (REL), especially for sampling erroneous packets; suggestion to move erroneous update logging to event-oriented messages.
BGP Operational Security Best Practices:
- Discussion on the scope and nature of the BGP operational security best practices document, including potential for it being used as inspiration for policy and laws.
- Proposal to split the current draft into a BCP (high-level principles), an informational document (techniques), and a terminology document.
- Concerned about the document's maintainability and the need to avoid excessive detail that can quickly become outdated.
BMP Statistics and Reporting:
- Presentation of new BMP stat types and definitions for aggregated BMP route monitor messages.
- Discussion on the feasibility and usefulness of the proposed new stat counters, particularly the impact on router performance.
- Suggestion to leverage existing BMP extensions for the various Palo BMP extensions
- Suggestion to refactor the counters to be built on the Yang modules.
TCP AO for BMP:
- Discussion on standardizing TCP AO for BMP and supporting it as a supported profile to encourage vendors to implement it.
- Support for producing a small RFC specifying the use of TCP AO for BMP.

Decisions and Action Items

Peering API: The chair will issue a call for working group adoption of the peering API draft.
BGP Operational Security Best Practices: The draft will be slimmed down to focus on high-level principles, with separate informational documents created for terminology and techniques.
BMP Statistics and Reporting: The presenter will follow-up on existing Yang Models to address the proposed statistics.
TCP AO for BMP: A formal request to adopt a short RFC specifying TCP AO for BMP will be made.

Next Steps

Discussion of the peering API at the side meeting on March 21st.
