A new Request for Comments is now available in online RFC libraries. RFC 9131 Title: Gratuitous Neighbor Discovery: Creating Neighbor Cache Entries on First-Hop Routers Author: J. Linkova Status: Standards Track Stream: IETF Date: October 2021 Mailbox: furry@google.com Pages: 20 Updates: RFC 4861 I-D Tag: draft-ietf-6man-grand-07.txt URL: https://www.rfc-editor.org/info/rfc9131 DOI: 10.17487/RFC9131 Neighbor Discovery (RFC 4861) is used by IPv6 nodes to determine the link-layer addresses of neighboring nodes as well as to discover and maintain reachability information. This document updates RFC 4861 to allow routers to proactively create a Neighbor Cache entry when a new IPv6 address is assigned to a node. It also updates RFC 4861 and recommends that nodes send unsolicited Neighbor Advertisements upon assigning a new IPv6 address. These changes will minimize the delay and packet loss when a node initiates connections to an off-link destination from a new IPv6 address. This document is a product of the IPv6 Maintenance Working Group of the IETF. This is now a Proposed Standard. STANDARDS TRACK: This document specifies an Internet Standards Track protocol for the Internet community, and requests discussion and suggestions for improvements. Please refer to the current edition of the Official Internet Protocol Standards (https://www.rfc-editor.org/standards) for the standardization state and status of this protocol.
