Summary

The IDR working group meeting covered a range of topics including working group status updates, adoption calls, and presentations on various draft proposals. Key areas of discussion included BGP Class Transfer Templates (Ct), extensions for SR policy advertisement, YANG models for BGP, and solutions for connecting IPv4 islands over IPv6 cores. Several presentations focused on addressing specific issues and enhancements to existing drafts, with calls for working group review and implementation feedback.

Key Discussion Points

Working Group Status: Updates on completed and ongoing work, including RFC publications and drafts progressing through the IETF queue.
Adoption Calls: Status of adoption calls for several drafts, with a reminder to provide feedback on drafts nearing adoption decisions.
BGP Class Transfer Templates (Ct) & BGP Card: Progress updates on these drafts, focusing on addressing issues raised in the Github repositories, and demonstrations of interoperability.
