 * `dhcp_config_path` - (Optional) Policy path to DHCP server or relay configuration to use for this gateway.
 * `rd_admin_address` - (Optional) Route distinguisher administrator address. If using EVPN service, then this attribute should be defined if auto generation of route distinguisher on VRF configuration is needed.
