$1$d will forward along z$1$ since OSPF has computed the path to $1$c is via z$1.$

$1$d will forward along z$2$ since OSPF has computed the path to $1$c is via z$2.$

$1$d will forward along z$1$ since BGP has computed the path to $1$c is via z$1.$

$1$d will forward along z$2$ since BGP has computed the path to $1$c is via z$2.$

$1$d will forward along z$1$ since hot potato routing forwards clockwise.
