  We study the baryogenesis via leptogenesis in a class of left-right symmetric
models, in which $D$-parity is broken spontaneously. We first discuss the
consequence of the spontaneous $D$-parity breaking on the neutrino masses. Than
we study the lepton asymmetry in various cases, from the decay of right handed
neutrino as well as the triplet Higgs, depending on their relative masses they
acquire from the symmetry breaking pattern. The leptogenesis bound on their
masses are discussed by taking into account the low energy neutrino oscillation
data. It is shown that a TeV scale leptogenesis is viable if there are
additional sources of CP violation like domain wall originating from the
spontaneous $D$-parity violation.
