Registering an OpenStack Resource
After OpenStack Resources have been discovered by Cisco IAC 4.3.2, you can register the network resource, for
example, in same way as any other discovered resources can be registered. In addition, networks which are discovered
and registered need to be created as 'Shared' networks in OpenStack. This allows them to be used in Provisioning VDCs
using existing networks, as well as for Add Network to VDC.
