From f4011396e88647e9fbbb2b99b4cb6c6da54b70bd Mon Sep 17 00:00:00 2001 From: ChristopherPrice Date: Thu, 11 Aug 2016 08:25:14 +0200 Subject: Applying the userguide template for the SDN VPN userguide documentation. Added a draft of the scenario description template for consideration and review. This is a draft migrating the existing userguide text into the proposed feature project userguide format for Colorado. Please review and comment, correct and merge as needed. (this is the prototype) Change-Id: Ia82a0c3ba0f654efc2892aac3a3b2d217ed2ad27 Signed-off-by: ChristopherPrice --- .../os-odl_l2-bgpvpn/scenario.description.rst | 69 ++++++++++++++++++++++ 1 file changed, 69 insertions(+) create mode 100644 docs/scenarios/os-odl_l2-bgpvpn/scenario.description.rst (limited to 'docs/scenarios/os-odl_l2-bgpvpn/scenario.description.rst') diff --git a/docs/scenarios/os-odl_l2-bgpvpn/scenario.description.rst b/docs/scenarios/os-odl_l2-bgpvpn/scenario.description.rst new file mode 100644 index 0000000..b7ef93a --- /dev/null +++ b/docs/scenarios/os-odl_l2-bgpvpn/scenario.description.rst @@ -0,0 +1,69 @@ +..
