If an endpoint is allowed to have multiple addresses and allowed to rapidly change addresses then a more optimal last-mile solution is dynamic topological address delegation. Each IP represents a current-best-path coreward through the ISP's network. When the path changes, so do the downstream addresses. Instead of a routing protocol you have an addressing protocol. In theory, such a thing automatically aggregates into very small routing tables. Very much a work in progress: http://bill.herrin.us/network/name/nr1.gif http://bill.herrin.us/network/name/nr2.gif http://bill.herrin.us/network/name/nr3.gif Regards, Bill Herrin -- William D.
