+  NeutronEnableIsolatedMetadata:

+    description: If True, DHCP provide metadata route to VM.

+  NeutronDnsmasqOptions:
+    default: 'dhcp-option-force=26,%MTU%'
+    description: >
+      Dnsmasq options for neutron-dhcp-agent. The default value here forces MTU
+      to be set to the value of NeutronTenantMtu, which should be set to account
+      for tunnel overhead.
+    type: string
+  NeutronTenantMtu:
+    description: >
+      The default MTU for tenant networks. For VXLAN/GRE tunneling, this should
+      be at least 50 bytes smaller than the MTU on the physical network. This
+      value will be used to set the MTU on the virtual Ethernet device.
+      This value will be used to construct the NeutronDnsmasqOptions, since that
+      will determine the MTU that is assigned to the VM host through DHCP.
