Function Documentation

◆ EvrNetNDP_AddressNotLinkLocal()

__STATIC_INLINE void EvrNetNDP_AddressNotLinkLocal ( uint16_t  if_id,
const uint8_t *  ip6_addr

Parameters
if_idnetwork interface identifier
ip6_addrpointer to IPv6 source address
Remarks
Nodes must silently discard RA messages if source IP not link-local.

The event AddressNotLinkLocal is created when the network library receives the router advertisement message, but the source IPv6 address is not link-local. The frame is therefore discarded.

Value in the Event Recorder shows:

  • netif: network interface identifier.
  • src_addr: source IPv6 address of received RA message.

◆ EvrNetNDP_CacheAdd()

Parameters
if_idnetwork interface identifier
ip6_addrpointer to IPv6 address
