The IPBOOTP_IF_CONFIG structure is used to set or retrieve the per-interface configuration. This is used in the following methods:

• RRouterInterfaceTransportAdd (section 3.1.4.18) 

• RRouterInterfaceTransportGetInfo (section 3.1.4.19) 

• RRouterInterfaceTransportSetInfo (section 3.1.4.20) 

All IP address are in network order.

 typedef struct _IPBOOTP_IF_CONFIG {
   DWORD IC_State;
   DWORD IC_RelayMode;
   DWORD IC_MaxHopCount;
   DWORD IC_MinSecondsSinceBoot;
 } IPBOOTP_IF_CONFIG,
  *PIPBOOTP_IF_CONFIG;

IC_State: Contains the status of the IPBOOTP. This member is read only.

Value	Meaning
IPBOOTP_STATE_ENABLED 0x00000001	The interface is enabled.
IPBOOTP_STATE_BOUND 0x00000002	The socket is bound and can listen to the IP BOOTP packets [RFC1542].

IC_RelayMode: Contains the IPBOOTP relay mode status. It MUST be one of the following values.

Value	Meaning
IPBOOTP_RELAY_DISABLED 0x00000000	The relay is configured.
IPBOOTP_RELAY_ENABLED 0x00000001	The relay is not configured.

IC_MaxHopCount: The maximum number of DHCP relay agents that will handle the DHCP relayed traffic. It MUST be less than 17.

IC_MinSecondsSinceBoot: The number of seconds the relay agent waits before forwarding the DHCP messages; no validation is done while setting this value.
