From 413652910234f44e11d6550abf6871621474b8cb Mon Sep 17 00:00:00 2001 From: Hans Dedecker Date: Mon, 23 Apr 2018 13:32:19 +0200 Subject: dhcpv6-ia: keep tentative assignments alive for a short time Assign tentative assignments a lifetime of 60 seconds; this will assure the assignment is seen as valid during lookup when receiving a later REQUEST from the DHCPv6 client.
