Well if you are speaking of changing the route type, you could do that
from the source yes. But not at the destination, and even if you could
at RouterD can you make it affect only one neighbor. Only one path can
be chosen, if the distance was changed then it would be the same for
both paths out. Are you suggesting something different? I really think
the only way to do it is via local policy routing and not within OSPF.
Thanks,

It is OSPF and the routers are in area 0. I don't think it can be done

Smith,
What routing protocol are you using? If ospf, are the routers
in question in the same area?

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..

Importance: Low
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.
