The "shimming" model is a way to solve this by the endsystems knowing about multihoming, instead of the network. I personally think this is a better idea and scales much better. Let's have the network moving packets as its primary goal, not solving "how do I reach this prefix" equations.
Waitaminute - isn't the whole *purpose* of layer 3 that the network makes these routing decisions? If there are N routers in an ISP, I would expect the ISP to connect to X endsystems, where 10N < X < 1000N. How does knowing about X endsystems scale better than knowing about N intermediate systems? Am I missing something here? David Barak http://www.listentothefranchise.com __________________________________ Yahoo! Mail - PC Magazine Editors' Choice 2005 http://mail.yahoo.com
