From 95c385b4d5a71b8ad552aecaa968ea46d7da2f6a Mon Sep 17 00:00:00 2001 From: Neil Horman Date: Wed, 25 Apr 2007 17:08:10 -0700 Subject: [IPV6] ADDRCONF: Optimistic Duplicate Address Detection (RFC 4429) Support. Nominally an autoconfigured IPv6 address is added to an interface in the Tentative state (as per RFC 2462). Addresses in this state remain in this state while the Duplicate Address Detection process operates on them to determine their uniqueness on the network. During this period, these tentative addresses may not be used for communication, increasing the time before a node may be able to communicate on a network. Using Optimistic Duplicate Address Detection, autoconfigured addresses may be used immediately for communication on the network, as long as certain rules are followed to avoid conflicts with other nodes during the Duplicate Address Detection process.
