Like MPLS or asymmetric routing... Noone wants unnecessarily confused employees or customers, but I don't think confusing traceroute output comes very high on the network design criteria list these days :) Whether the savings are useless depends on how you count the cost. Address space savings are of course pointless, but managing address allocations does have a cost. It doesn't have to be high, but it is a cost you have to consider. FWIW, we decided to go with an IA_NA based WAN GUA for CPE management purposes - we needed a management address and didn't want to steal from the customers IA_PD prefix. Bjørn
