Gratuitous Neighbor Discovery: Creating Neighbor Cache Entries on First-Hop Routers
RFC 9131

Received changes through RFC Editor sync (created alias RFC 9131, changed abstract to '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.', changed pages to 20, changed standardization level to Proposed Standard, changed state to RFC, added RFC published event at 2021-10-01, changed IESG state to RFC Published, created updates relation between draft-ietf-6man-grand and RFC 4861)
