EXACTLY, THAT IS NOT GOING TO WORK, BECAUSE OF THE SAME ROUTER ID of the only router who originated the route... lest see what the experts here can tell us.. Im also guessing how can we achive de desired goal

 It is not going to work because when router changes the AD it can be
changed on specific routes for the neighbor who originated it.
So when Router D recieves routes it changes the AD for that Route but
for both of the equal cost path Routes and not for a single path coz
both have been originated by same Router.

I have labbed it can show you..

you can change the administrative distance of the "prefered" or selected
routes per neighbor, you select the routes where you want to change to a
value less than the default with an acl, then you select the neighbor
router who is sending you routes via the prefered path and change the
distance of only the selected route from the acl. thus you can
manipulate the path to certaing given routes over a prefered path.
