Disagree, that conclusion doesn't follow (and in my experience it's wrong). Overlap/collision happens when there are two interfaces on the same host (even if they're not in use simultaneously). The collisions can affect the routing table (if the host implements in such a way), ACLs like in host firewall policies and such, and various application-layer uses. It's fine to specify use as the default range (e.g. for 464xlat or DS-lite) but important to never constrain it to only that range, assuming the range is made non-DS-lite specific. -Dave
