RTM_IP_ROUTE structure

[This API has been superseded by the Routing Table Manager Version 2 API and will not be available beyond Windows Server 2003. Applications should use the Routing Table Manager Version 2 API.]

The RTM_IP_ROUTE structure contains information that describes a route owned by the IP protocol family.

Syntax

typedef struct _RTM_IP_ROUTE {
  FILETIME               RR_TimeStamp;
  DWORD                  RR_RoutingProtocol;
  DWORD                  RR_InterfaceID;
  PROTOCOL_SPECIFIC_DATA RR_ProtocolSpecificData;
  IP_NETWORK             RR_Network;
  IP_NEXT_HOP_ADDRESS    RR_NextHopAddress;
  IP_SPECIFIC_DATA       RR_FamilySpecificData;
} RTM_IP_ROUTE, *PRTM_IP_ROUTE;

Members

RR_TimeStamp

Specifies the time that the route entry was created or last updated. This member is set by the routing table manager. The time is expressed as a FILETIME structure.

RR_RoutingProtocol

Specifies the routing protocol that added the route.

RR_InterfaceID

Specifies the interface through which the route was obtained.

RR_ProtocolSpecificData

Specifies a PROTOCOL_SPECIFIC_DATA structure that contains memory reserved for routing-protocol-specific data.

RR_Network

Specifies an IP_NETWORK structure that contains an IP network address.

RR_NextHopAddress

Specifies an IP_NEXT_HOP_ADDRESS structure that contains the address of the next-hop router.

RR_FamilySpecificData

Specifies an IP_SPECIFIC_DATA structure that contains IP protocol-family-specific data.

Remarks

The members of the RTM_IP_ROUTE structure are all DWORD aligned.
