The IESG has approved the following document: - 'Neighbor Discovery Considerations in IPv6 Deployments' (draft-ietf-v6ops-nd-considerations-14.txt) as Informational RFC This document is the product of the IPv6 Operations Working Group. The IESG contact persons are Mahesh Jethanandani and Mohamed Boucadair. A URL of this Internet-Draft is: https://datatracker.ietf.org/doc/draft-ietf-v6ops-nd-considerations/ Technical Summary This document summarizes published Neighbor Discovery (ND) issues and then describes how all these issues originate from three causes. This document also analyzes the mitigation solutions and demonstrates that isolating hosts into different subnets and links can help to address the three causes. Guidance is provided for selecting a suitable isolation method to prevent potential ND issues. Working Group Summary There was good discussion between working group, and little controversy. Document Quality Neighbor Discovery (ND) is a critical part of IPv6, but discussion, considerations and issue mitigation is spread across ~20 RFCs. This document contains a summary of those documents to allow implementers and operators to understand the implications, as well as mitigations for some deployment issues. Personnel The Document Shepherd for this document is Timothy Winters. The Responsible Area Director is Mohamed Boucadair.
