If source address is from the link-local scope, then check that it is loopback. If so, then it must be received on the loopback interface. Based on the receiving interface and destination address scope, determine the corresponding ifaddr. If destination address has link-local scope and ifaddr wasn't found, this means that the address is from the different zone. END
