you can use rigidLink.
try this command

if you used the equalDOF commmand and they are not equal: 1) you messed up, 2) you used a penalty constraint handler and the penalty factors are not large enough, 3) you tried to enforce one node consrained to another constrained to another and you ignored the warning messages.
