// DrgRouteRule A DRG route rule is a mapping between a destination IP address range and a DRG attachment.
// The map is used to route matching packets. Traffic will be routed across the attachments using Equal-cost multi-path routing (ECMP)
// if there are multiple rules with identical destinations and none of the rules conflict.
type DrgRouteRule struct {

	// Represents the range of IP addresses to match against when routing traffic.
	// Potential values:
	//   * An IP address range (IPv4 or IPv6) in CIDR notation. For example: `192.168.1.0/24`
	//   or `2001:0db8:0123:45::/56`.
	//   * When you're setting up a security rule for traffic destined for a particular `Service` through
	//   a service gateway, this is the `cidrBlock` value associated with that Service. For example: `oci-phx-objectstorage`.
	Destination *string `mandatory:"true" json:"destination"`

	// The type of destination for the rule.
	// Allowed values:
	//   * `CIDR_BLOCK`: If the rule's `destination` is an IP address range in CIDR notation.
	//   * `SERVICE_CIDR_BLOCK`: If the rule's `destination` is the `cidrBlock` value for a
	//     Service (the rule is for traffic destined for a
	//     particular `Service` through a service gateway).
	DestinationType DrgRouteRuleDestinationTypeEnum `mandatory:"true" json:"destinationType"`

	// The OCID (https://docs.oracle.com/iaas/Content/General/Concepts/identifiers.htm) of the next hop DRG attachment responsible
	// for reaching the network destination.
	// A value of `BLACKHOLE` means traffic for this route is discarded without notification.
	NextHopDrgAttachmentId *string `mandatory:"true" json:"nextHopDrgAttachmentId"`

	// The Oracle-assigned ID of the DRG route rule.
	Id *string `mandatory:"true" json:"id"`

	// The earliest origin of a route. If a route is advertised to a DRG through an IPsec tunnel attachment,
	// and is propagated to peered DRGs via RPC attachments, the route's provenance in the peered DRGs remains `IPSEC_TUNNEL`,
	// because that is the earliest origin.
	// No routes with a provenance `IPSEC_TUNNEL` or `VIRTUAL_CIRCUIT` will be exported to IPsec tunnel or virtual circuit attachments,
	// regardless of the attachment's export distribution.
	RouteProvenance DrgRouteRuleRouteProvenanceEnum `mandatory:"true" json:"routeProvenance"`

	// You can specify static routes for the DRG route table using the API.
	// The DRG learns dynamic routes from the DRG attachments using various routing protocols.
	RouteType DrgRouteRuleRouteTypeEnum `mandatory:"false" json:"routeType,omitempty"`

	// Indicates that the route was not imported due to a conflict between route rules.
	IsConflict *bool `mandatory:"false" json:"isConflict"`

	// Indicates that if the next hop attachment does not exist, so traffic for this route is discarded without notification.
	IsBlackhole *bool `mandatory:"false" json:"isBlackhole"`

	// Additional properties for the route, computed by the service.
	Attributes *interface{} `mandatory:"false" json:"attributes"`
