I've been searching for quite a while and experimenting but there must
be an extra step I am missing to get a simple inband controller example
to work. Here is the simple example topology.
s2---s1---controller
s1 = 11.0.0.1/32
s2 = 11.0.0.2/32
controller = 11.0.0.100/8
An example ovs-vsctl show.
Bridge "s1"
Controller "tcp:11.0.0.100:6633"
fail_mode: secure
Port "s1-eth1"
Interface "s1-eth1"
Port "s1-eth2"
Interface "s1-eth2"
Port "s1-eth12"
Interface "s1-eth12"
Port "s1"
Interface "s1"
type: internal
ovs_version: "1.10.0"
# ovs-ofctl show s1

The part I am having a hard time figuring out is getting either
switch to talk to the controller. Even the one connected to the
controller. What is the correct OF entry that I can manually add to
each switch to start talking? For s1, I thought just adding a flow
entry for ip=11.0.0.100 action=output:1. But that didn't seem to work.
I've seem many many threads on the topic, but none of them seem to
have shared the final conclusion on how they did it.
Thanks,
Greg
