gen var3 = var1 == var2
is certainly a good way to create a variable saying whether two
variables are the same. But what do you mean that "this is not
working"?
Note that -- necessarily -- this syntax compares values in the same
observation, and not in different observations.
gen var4 = var1 == var2[_n-1]
illustrates an extension which may be closer to what you seek.
