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?
I think there's some misunderstanding. Nothing has to know about X endsystems. Nor did anything have to know about N routers before. In the shim6 approach, a host only needs to know about its correspondent hosts. From a scalability perspective, this is unchanged from previously, only the constants are bigger. Tony
