Juan:
Administrative distance is local to a router- it isn't advertised to other
routers. AD's aren't sent in routing updates.
The receiving router will have an AD of either 90 or 170, depending on
whether it is an internal or external EIGRP route. The AD of the sending
router doesn't affect it at all.
If you want to change the AD of a specific route on the receiving router,
you have to use the distance command inside eigrp on the receiving router,
along with an access-list to specify which advertising source you are
referring to. Check the archives for examples- some IOS's have a bug in the
description, asking for a wildcard mask when they really want a subnet mask
(Or vice-versa, I forget- but its in the archives.).
