4.9.2 Workflow Steps
1. Set the inputs for the library workflows such as VCD host, network names and descriptions, and set if the network is port group-based.
2. Invoke a user interaction with the following inputs:
*External network name and description (default name and description provided, names can be edited).
*External network specification including:
*Network mask (mandatory).
*Default gateway (mandatory).
*Primary DNS.
*Secondary DNS.
*DNS suffix.
*Address pool for static IP allocation (mandatory).
*Organization virtual datacenter network:
*Name.
*Description.
*Share this network with other virtual datacenters.
*Run the Add an External Network workflow from the library.
*Run the Add an Organization VDC Network workflow from the library.
User interaction is needed because some of the parameters, such as the IP address pool, cannot be determined automatically.
