From 1b630f8bc59978884c9caccebca3b6d8e9b045a1 Mon Sep 17 00:00:00 2001 From: Hans Dedecker Date: Tue, 21 Feb 2017 09:54:36 +0100 Subject: [PATCH] router: don't announce prefixes with valid lifetime equal to 0 Don't set prefix valid lifetime to 0 in case the preferred lifetime equals 0 and valid lifetime gets smaller than 7200. In corner cases it leads to router lifetime being set although no prefixes are announced with a valid lifetime different from 0.
