From 92a81c34ece6b28b599acc822a9b54f9a26324a3 Mon Sep 17 00:00:00 2001 From: Brian Haley Date: Fri, 8 Jan 2016 17:47:34 -0500 Subject: [PATCH] Increase default IPv6 router advertisement interval The current values of min:3 and max:10 mean radvd is sending an RA about every 7 seconds, which can be excessive when we have thousands of routers. Let's relax it by 10x since most VMs will send a Router Solicition at boot, obviating the need for a small interval.
