```ruby
module OpenStack
module Network
  class Network

  attr_reader :id
  attr_reader :name
  attr_reader :admin_state_up
  attr_reader :status
  attr_reader :subnets
  attr_reader :shared
  attr_reader :tenant_id

  def initialize(net_info={})
    @id = net_info["id"]
    @name = net_info["name"]
    @admin_state_up = net_info["admin_state_up"]
    @status = net_info["status"]
    @subnets = net_info["subnets"]
    @shared = net_info["shared"]
    @tenant_id = net_info["tenant_id"]
  end

  end

      attr_reader :tenant_id

      def initialize(net_info = {})
        @id = net_info['id']
        @name = net_info['name']
        @admin_state_up = net_info['admin_state_up']
        @status = net_info['status']
        @subnets = net_info['subnets']
        @shared = net_info['shared']
        @external = net_info['router:external']
        @tenant_id = net_info['tenant_id']
