Gang, I think there was some confusion about VA during the talk today, and I wanted to clear some things up:
1. VA does not require any new hardware. An "Aggregation Point Router" is a normal router that just happens to be an aggregation point for one or more virtual prefixes. 2. No router FIB need carry the entire DFZ. In our tier-1 ISP study, ALL routers saw 10x FIB reduction or more, NO routers saw more than a few percent load increase. The basic trade-off that VA offers to an ISP is whether to change out hardware or to increase the amount of config it has to do. I wouldn't want to presuppose that no ISP would prefer to increase config over change out hardware.
