  We investigate possible regimes in spatially flat vacuum cosmological models
in cubic Lovelock gravity. The spatial section is a product of three- and
extra-dimensional isotropic subspaces. This is the second paper of the series
and we consider D=5 and general D>=6 cases here. For each D case we found
critical values for $\alpha$ (Gauss-Bonnet coupling) and $\beta$ (cubic
Lovelock coupling) which separate different dynamical cases and study the
dynamics in each region to find all regimes for all initial conditions and for
arbitrary values of $\alpha$ and $\beta$. The results suggest that for D>=3
there are regimes with realistic compactification originating from `generalized
Taub' solution. The endpoint of the compactification regimes is either
anisotropic exponential solution (for $\alpha > 0$, $\mu \equiv \beta/\alpha^2
< \mu_1$ (including entire $\beta < 0$)) or standard Kasner regime (for $\alpha
> 0$, $\mu > \mu_1$). For D>=8 there is additional regime which originates from
high-energy (cubic Lovelock) Kasner regime and ends as anisotropic exponential
solution. It exists in two domains: $\alpha > 0$, $\beta < 0$, $\mu \leqslant
\mu_4$ and entire $\alpha > 0$, $\beta > 0$. Let us note that for D>=8 and
$\alpha > 0$, $\beta < 0$, $\mu < \mu_4$ there are two realistic
compactification regimes which exist at the same time and have two different
anisotropic exponential solutions as a future asymptotes. For D>=8 and $\alpha
> 0$, $\beta > 0$, $\mu < \mu_2$ there are two realistic compactification
regimes but they lead to the same anisotropic exponential solution. This
behavior is quite different from the Einstein-Gauss-Bonnet case. There are two
more unexpected observations among the results -- all realistic
compactification regimes exist only for $\alpha > 0$ and there is no smooth
transition from high-energy Kasner regime to low-energy one with realistic
compactification.
