Link-to child rout redirect to parent rout

I have router like this

Router.map(function() {
  this.route('messages-faxes', function() {
    this.route('inbox');
  });
  this.route('contacts', function(){
    this.route('new');
  });
});

In header of page i have nave bar with link to messages-faxes/inbox

To messages-faxes.index rout i add some code to redirect to messages-faxes.inbox

redirect: function(params) {
  this.transitionTo('messages-faxes.inbox');
}

If i click on link i have that backtrace in console

Preparing to transition from 'contacts.index' to 'messages-faxes.inbox' 
Transitioned into 'messages-faxes.inbox'
Preparing to transition from 'messages-faxes.inbox' to 'messages-faxes.index'
Transitioned into 'messages-faxes.inbox'

How to prevent transition from child rout(messages-faxes.inbox) to parent(messages-faxes.index)? Or it is good for ember?
