CPLEX how to get all the different optimal solutions with the same cost

Question

I have a problem solved by Cplex that has at least two different optimal solutions with the same value.

How can I get all the different optimal solutions with the same value?

Update: it is a linear programming problem

For MIP problems you can use the solution pool. For pure LP problems things are more difficult [[link](http://yetanothermathprogrammingconsultant.blogspot.com/2016/01/finding-all-optimal-lp-solutions-using.html)] — Erwin Kalvelagen, Oct 07 '17 at 19:57

You could as said at

use the solution pool or an artificial objective in order to enumerate solutions.
