+# Nicira NVP

+# ----------

+

+# This third-party addition can be used to configure connectivity between a DevStack instance

+# and an NVP Gateway in dev/test environments. In order to use this correctly, the following

+# env variables need to be set (e.g. in your localrc file):

+#

+# * enable_service nicira            --> to execute this third-party addition

+# * PUBLIC_BRIDGE                    --> bridge used for external connectivity, typically br-ex

+# * NVP_GATEWAY_NETWORK_INTERFACE    --> interface used to communicate with the NVP Gateway

+# * NVP_GATEWAY_NETWORK_CIDR         --> CIDR to configure br-ex, e.g. 172.24.4.211/24

+

+# Save trace setting

+MY_XTRACE=$(set +o | grep xtrace)

+set +o xtrace

+

+# This is the interface that connects the Devstack instance

+# to an network that allows it to talk to the gateway for

+# testing purposes
