  In this work, which follows a series of studies on the higher-dimensional
steady state universe idea and prepared for Professor Tekin Dereli's
Festschrift, we show the influence of the dynamical internal (unobservable)
space on the evolution of the possible anisotropy of the external (observable)
space. We obtain mathematically exactly the same Friedmann equation of the
standard $\Lambda$CDM model for the external space, but with some remarkable
physical differences. In particular, the higher-dimensional negative
cosmological constant plays the role of the four-dimensional positive
cosmological constant and the expansion anisotropy, viz., the shear scalar, of
the external space mimics a negative cosmological constant; it would mimic a
stiff fluid when allowed on top of the standard $\Lambda$CDM model. This latter
feature gives us the opportunity to manipulate the CMB quadrupole temperature
fluctuation, suggesting a possible answer to the fact that its observed value
is lower than that predicted by the standard $\Lambda$CDM model.
