  We present recent measurements of multijet correlations using forward and
low-$p_{\mathrm{T}}$ jets performed by the CMS collaboration at the LHC
collider. In pp collisions at $\sqrt{s} = 7$ TeV, azimuthal correlations in
dijets separated in rapidity by up to 9.4 units were measured. The results are
compared to BFKL- and DGLAP-based Monte Carlo generator and analytic
predictions. In pp collisions at $\sqrt{s} = 8$ TeV, cross sections for jets
with $p_{\mathrm{T}}$ > 21 GeV and |y| < 4.7, and for track-jets with
$p_{\mathrm{T}}$ > 1 GeV (minijets) are presented. The minijet results are
sensitive to the bound imposed by the total inelastic cross section, and are
compared to various models for taming the growth of the $2 \rightarrow 2$ cross
section at low $p_{\mathrm{T}}$.
