Drawing a border in odd and even pages

Like I said, use tpflip to design both eve and odd page styles.

usepackage{lipsum}

tikzset{
        secnode/.style={
                minimum height=1cm,
                inner xsep=20pt,
                rotate=90,
                anchor=north east,
                draw=white,
                fill=olive,
                text=white,
                blur shadow={shadow blur steps=5,shadow blur extra rounding=1.3pt}},
        pagenode/.style={
                minimum width=5mm,
                minimum height=1cm,
                inner sep=2pt,

                text=white,
                blur shadow={shadow blur steps=5,shadow blur extra rounding=1.3pt}}
        }
