-Notes and Advice:
 
-For scalable configurations, you may need to increase some of your kernel
-limits. For example, you could add something like the following to
-/etc/sysctl.conf:
-
-# OpenFlow: get rid of ipv6
-net.ipv6.conf.all.disable_ipv6 = 1
-net.ipv6.conf.default.disable_ipv6 = 1

-# Mininet: Increase open file limit
