Is there a way CPLEX can help to identify whether a linear programming model (continuous) has a unique optimal solution or Multiple optimal solutions. I tried to do this by setting the advanced start parameter CPX_PARAM_ADVIND to 1. After solving the same LP model twice, I found out that the optimal solutions returned for both runs are similar although the LP model solved has multiple solutions.
Any help on this will be very much appreciated.

You can use sensitivity analysis functions: http://orinanobworld.blogspot.com/2012/10/detecting-multiple-optima-in-lp.html
