In fact, the host cannot. There are a number of situations where a host could have the same Link-Local IP address on two or more interfaces. For example, i) If it is using a trunk protocol to connect to multiple vlans on a single NIC ii) If the Mac Address is not based on the NIC but on the CPU In this situation, the host would not be able to know which interface to listen on, without the zone id.
