OK, since it's so basic why don't you explain how to have router A dynamically learn from router B that there is a new subnet on the local ethernet? > Don't route IP blocks to the ethernet.

So then what do you call a connected route (for an ethernet interface on a router)? If you use ethernet, at the edges of your network you HAVE to route IP blocks to the ethernet. -Ralph
