I'm trying to resolve the second order DEQ

eqns = {Derivative[0, 1][f][x, t] == a*Derivative[2, 0][f][x, t],
Derivative[1, 0][f][0, t] == 0,Derivative[1,0][f][L,t]==0, f[x, 0] == DiracDelta[x]}

Dsolve[eqns, f[x, t], x]

but I keep getting it resolving those boundary conditions at x=0 and x=L as "True"

Thanks for any help
