+4. Make sure that the IPv6 is enabled on your environment. Some Ryu BGP
+features require the IPv6 connectivity to bind sockets. Mininet seems to
+disable IPv6 on its installation.
+
+ For example::
+
+ $ sysctl net.ipv6.conf.all.disable_ipv6
+ net.ipv6.conf.all.disable_ipv6 = 0 # should NOT be enabled
+
+ $ grep GRUB_CMDLINE_LINUX_DEFAULT /etc/default/grub
+ # please remove "ipv6.disable=1" and reboot
+ GRUB_CMDLINE_LINUX_DEFAULT="ipv6.disable=1 quiet splash"
+
+5. Make sure that your switch using the OpenFlow version 1.3. This application
+supports only the OpenFlow version 1.3.
+
+ For example::
+
+ $ ovs-vsctl get Bridge s1 protocols
+ ["OpenFlow13"]
+
+.. Note::
+
+ At the time of this writing, we use the the following version of Ryu,
+ Open vSwitch and Mininet.
+
+ ::
+
+ $ ryu --version
+ ryu 4.19
+
+ $ ovs-vsctl --version
+ ovs-vsctl (Open vSwitch) 2.5.2 # APT packaged version of Ubuntu 16.04
