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.

Parameters
[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.
