ROUTING_PROTOCOL_CONFIG structure (mgm.h)

  • Article

The ROUTING_PROTOCOL_CONFIG structure describes the routing protocol configuration information that is passed to the multicast group manager when a protocol registers with the multicast group manager.

Syntax

typedef struct _ROUTING_PROTOCOL_CONFIG {
  DWORD                        dwCallbackFlags;
  PMGM_RPF_CALLBACK            pfnRpfCallback;
  PMGM_CREATION_ALERT_CALLBACK pfnCreationAlertCallback;
  PMGM_PRUNE_ALERT_CALLBACK    pfnPruneAlertCallback;
  PMGM_JOIN_ALERT_CALLBACK     pfnJoinAlertCallback;
  PMGM_WRONG_IF_CALLBACK       pfnWrongIfCallback;
  PMGM_LOCAL_JOIN_CALLBACK     pfnLocalJoinCallback;
  PMGM_LOCAL_LEAVE_CALLBACK    pfnLocalLeaveCallback;
  PMGM_DISABLE_IGMP_CALLBACK   pfnDisableIgmpCallback;
  PMGM_ENABLE_IGMP_CALLBACK    pfnEnableIgmpCallback;
} ROUTING_PROTOCOL_CONFIG, *PROUTING_PROTOCOL_CONFIG;

Members

dwCallbackFlags

Reserved for future use.

pfnRpfCallback

Callback into a routing protocol to perform an RPF check.

pfnCreationAlertCallback

Callback into a routing protocol to determine the subset of interfaces owned by the routing protocol on which a multicast packet from a new source or to a new group should be forwarded.

pfnPruneAlertCallback

Callback into a routing protocol to notify the protocol that receivers for the specified source and group are no longer present on an interface owned by other routing protocols.

pfnJoinAlertCallback

Callback into a routing protocol to notify the protocol that new receivers for the specified source and group are present on an interface owned by another routing protocol.

pfnWrongIfCallback

Callback into a routing protocol to notify the protocol that a packet has been received from the specified source and for the specified group on the wrong interface.

pfnLocalJoinCallback

Callback into a routing protocol to notify the protocol that IGMP has detected new receivers for a group on an interface.

pfnLocalLeaveCallback

Callback into a routing protocol to notify the protocol that IGMP has detected that there are no more receivers for a group on an interface.

pfnDisableIgmpCallback

Callback into IGMP to notify IGMP that a protocol is taking or releasing ownership of an interface on which IGMP is enabled.

pfnEnableIgmpCallback

Callback into IGMP to notify IGMP that a protocol has finished taking or releasing ownership of an interface on which IGMP is enabled.
