Teco, the problem is simple: host-based routes are not preferrable. Host-based routes in routers surrounding router X (this is what a /128 address on a virtual interface on router X implies, be that loopback interface or not loopback interface) for a dynamically changing topology may lead to too many routes coming up and down, too many specific entries in the routing tables, too much dedicated routing messaging, and more. That only for the network itself. Connecting it to the Internet, with host-based routes propagated up and down throughout, may risk influencing the routes in the Internet proper. A new host-based route inserted in the routing table of the gateway connecting this network to the Internet may propagate throughout the entire fixed access system. If you told me which part of the above were unclear I could explain further. But I think there's large agreement on it. About the feasibility of _one_ /128 address on 'lo' while using _one_ host-based route: as you pointed out with the ios-linux example, I fully agree a /128 address assigned on the 'lo' interface of one computer, and a host-based route in the other computer towards that /128 address - will work. But just one. About posting to v6ops: which part do you think I should post there? About singling me out being the first and only mentioning some problem: I can only be happy about it and stop posting :-) But this host-based route stuff is not new, I'm myself surprised I'm singled out about it.
