Border Router

This module includes functions to manage local network data with the OpenThread Border Router.

Summary

Functions
`otBorderRouterAddOnMeshPrefix(otInstance aInstance, const otBorderRouterConfig aConfig)`	`otError` Add a border router configuration to the local network data.

`otBorderRouterGetNextOnMeshPrefix(otInstance aInstance, otNetworkDataIterator aIterator, otBorderRouterConfig *aConfig)`	`otError` This function gets the next On Mesh Prefix in the local Network Data.
`otBorderRouterGetNextRoute(otInstance aInstance, otNetworkDataIterator aIterator, otExternalRouteConfig *aConfig)`	`otError` This function gets the next external route in the local Network Data.
`otBorderRouterRegister(otInstance *aInstance)`	`otError` Immediately register the local network data with the Leader.
`otBorderRouterRemoveOnMeshPrefix(otInstance aInstance, const otIp6Prefix aPrefix)`	`otError` Remove a border router configuration from the local network data.
`otBorderRouterRemoveRoute(otInstance aInstance, const otIp6Prefix aPrefix)`	`otError` Remove an external route configuration from the local network data.

Functions

otBorderRouterAddOnMeshPrefix

otError otBorderRouterAddOnMeshPrefix(
  otInstance *aInstance,
  const otBorderRouterConfig *aConfig
)

Add a border router configuration to the local network data.

Details

Parameters

`[in] aInstance`	A pointer to an OpenThread instance.
`[in] aConfig`	A pointer to the border router configuration.

Return Values

`OT_ERROR_NONE`	Successfully added the configuration to the local network data.
`OT_ERROR_INVALID_ARGS`	One or more configuration parameters were invalid.
`OT_ERROR_NO_BUFS`	Not enough room is available to add the configuration to the local network data.

otBorderRouterAddRoute

otError otBorderRouterAddRoute(
  otInstance *aInstance,
  const otExternalRouteConfig *aConfig
)

Add an external route configuration to the local network data.

Details

Parameters

`[in] aInstance`	A pointer to an OpenThread instance.
`[in] aConfig`	A pointer to the external route configuration.

Return Values

`OT_ERROR_NONE`	Successfully added the configuration to the local network data.
`OT_ERROR_INVALID_ARGS`	One or more configuration parameters were invalid.

otBorderRouterGetNetData

otError otBorderRouterGetNetData(
  otInstance *aInstance,
  bool aStable,
  uint8_t *aData,
  uint8_t *aDataLength
)

This method provides a full or stable copy of the local Thread Network Data.

Details

Parameters

`[in] aInstance`	A pointer to an OpenThread instance.
`[in] aStable`	TRUE when copying the stable version, FALSE when copying the full version.
`[out] aData`	A pointer to the data buffer.
`[in,out] aDataLength`	On entry, size of the data buffer pointed to by `aData`. On exit, number of copied bytes.

otBorderRouterGetNextOnMeshPrefix

otError otBorderRouterGetNextOnMeshPrefix(
  otInstance *aInstance,
  otNetworkDataIterator *aIterator,
  otBorderRouterConfig *aConfig
)

This function gets the next On Mesh Prefix in the local Network Data.

Details

Parameters

`[in] aInstance`	A pointer to an OpenThread instance.
`[in,out] aIterator`	A pointer to the Network Data iterator context. To get the first on-mesh entry it should be set to OT_NETWORK_DATA_ITERATOR_INIT.
`[out] aConfig`	A pointer to the On Mesh Prefix information.

Return Values

`OT_ERROR_NONE`	Successfully found the next On Mesh prefix.
`OT_ERROR_NOT_FOUND`	No subsequent On Mesh prefix exists in the Thread Network Data.

otBorderRouterGetNextRoute

otError otBorderRouterGetNextRoute(
  otInstance *aInstance,
  otNetworkDataIterator *aIterator,
  otExternalRouteConfig *aConfig
)

This function gets the next external route in the local Network Data.

Details

Parameters

`[in] aInstance`	A pointer to an OpenThread instance.
`[in,out] aIterator`	A pointer to the Network Data iterator context. To get the first external route entry it should be set to OT_NETWORK_DATA_ITERATOR_INIT.
`[out] aConfig`	A pointer to the External Route information.

Return Values

`OT_ERROR_NONE`	Successfully found the next External Route.
`OT_ERROR_NOT_FOUND`	No subsequent external route entry exists in the Thread Network Data.

otBorderRouterRegister

otError otBorderRouterRegister(
  otInstance *aInstance
)

Immediately register the local network data with the Leader.

Details

Parameters

[in] aInstance

A pointer to an OpenThread instance.

Return Values

OT_ERROR_NONE

Successfully queued a Server Data Request message for delivery.
