Distance can't be altered for external EIGRP routes on a prefix-by-prefix
basis. You can change all but not individual routes.
Thanks for your help-
Alsontra- Below is a snip-it from the archives -
*******************************************************************
Router eigrp 10
distance eigrp 50 150
-With that you can change AD for both Internal and external. But this will
change the AD of all EIGRP routes on this particular router.
Router eigrp 10
distance 40 137.20.13.1 0.0.0.0 ----> will change AD only for Internal
routes learned from 137.20.13.1 neighbor.
"You can't change AD for specific external routes or external routes
learned"
from a particular neighbor in EIGRP.
Hope this clarify
