# VMware NSX

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

 # and an NSX 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 vmware_nsx        --> to execute this third-party addition

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

 # * NSX_GATEWAY_NETWORK_INTERFACE    --> interface used to communicate with the NSX Gateway
 # * NSX_GATEWAY_NETWORK_CIDR         --> CIDR to configure br-ex, e.g. 172.24.4.211/24

 
 # Save trace setting
 MY_XTRACE=$(set +o | grep xtrace)

 # This is the interface that connects the Devstack instance
 # to an network that allows it to talk to the gateway for
 # testing purposes
