peered_network is the network resource URL of the network
that is peered to the service provider network. Must be of
the format
projects/NETWORK_PROJECT_NUMBER/global/networks/NETWORK_NAME,
where NETWORK_PROJECT_NUMBER is the project number of the
Cloud project that holds your VPC network and NETWORK_NAME
is the name of your VPC network. If peered_network is
omitted or empty, the pool will use endpoints that are
publicly available.
