Subject: Re: ODL OVSDB hardware vtep support initial kick-off
Sending output of my experimentation to ovsdb-dev.
# This is a script that I had written to document my experimentation # using 4 machines:
#
# [A]----(b)----[C]----(d)----[E]----(f)----[G]
# [A] - Physical Server #1 (it was actually a Linux end host)
# (b) - IP over Ethernet link connecting server #1 to switch #1
# [C] - Physical Switch #1 with VTEP functionality (in my setup
# this was actually a Linux server with 2 NIC running OVS)
# (d) - VXLAN tunnel over IP over L2 Ethernet.
# [E] - Like [C], but for the other side
# (f) - Like (b), but for the other side
# [G] - like [A], but for the other side
#
# OVS should not be installed on [C] or [E] as part of the OS install.
# When InstallOVS is set to '1', the script downloads and compiles OVS.
# It then installs OVS under ~/Desktop/
#
#
# Disclaimer:
# -----------
# This is not production ready and MUST not be run directly. It makes # a lot of assumptions about the underlying server & OS.
#
# Please use the script (i.e. the commands listed here-in) as a starting # point and customize the same as appropriate for your scenario.
#
# Personal, I don't run the script directly. Instead I copy and paste # the commands one-at-a-time to my console session.
#
# The commands should be run as an oridinary user. sudo is used to get # root access as needed.
