Functions#
Handles ICMP6 RA messages received on the Thread interface on the platform.
Process a prefix received from the DHCPv6 PD Server.
Function Documentation#
otPlatBorderRoutingProcessIcmp6Ra#
void otPlatBorderRoutingProcessIcmp6Ra (otInstance * aInstance, const uint8_t * aMessage, uint16_t aLength)
Handles ICMP6 RA messages received on the Thread interface on the platform.
[in] | aInstance | A pointer to an OpenThread instance. |
[in] | aMessage | A pointer to an ICMPv6 RouterAdvertisement message. |
[in] | aLength | The length of ICMPv6 RouterAdvertisement message. |
The aMessage
should point to a buffer of a valid ICMPv6 message (without IP headers) with router advertisement as the value of type field of the message.
When DHCPv6 PD is disabled, the message will be dropped silently.
Note: RA messages will not be forwarded into Thread networks, while for many platforms, RA messages is the way of distributing a prefix and other infomations to the downstream network. The typical usecase of this function is to handle the router advertisement messages sent by the platform as a result of DHCPv6 Prefix Delegation.
Requires OPENTHREAD_CONFIG_BORDER_ROUTING_DHCP6_PD_ENABLE

otPlatBorderRoutingProcessDhcp6PdPrefix#
void otPlatBorderRoutingProcessDhcp6PdPrefix (otInstance * aInstance, const otBorderRoutingPrefixTableEntry * aPrefixInfo)
Process a prefix received from the DHCPv6 PD Server.
[in] | aInstance | A pointer to an OpenThread instance. |
[in] | aPrefixInfo | A pointer to the prefix information structure |
The prefix is received on the DHCPv6 PD client callback and provided to the Routing Manager via this API.
The prefix lifetime can be updated by calling the function again with updated time values. If the preferred lifetime of the prefix is set to 0, the prefix becomes deprecated. When this function is called multiple times, the smallest prefix is preferred as this rule allows choosing a GUA instead of a ULA.
Requires OPENTHREAD_CONFIG_BORDER_ROUTING_DHCP6_PD_ENABLE
