Hi Scott,
Thank you very much, i'll make sure to eliminate all those tedious routing
loops, but one last question if i may, if i was told to use AD, and i used
a conjunction of AD and tagging + filtering, am i ok with that or what, as
most of the scenarios won't go fine with just manipulating the AD.
Thank you again both of you Brian and Scott for your influence in the
field.
BR,
Mohammed Mahmoud.
