There may be a couple of areas where some small amount of protocol specification work would be required for the flow-through model: * the requesting router would have to know to accept delegated prefixes from multiple delegating routers rather than just choosing one delegating router * either each server would have to have its own set of relay agents, or a single set of relay agents would have to be provisioned dynamically with the list of delegating routers - Ralph > > The reason homenet didn't go with this solution is essentially that HNCP has > a better feature set and is easier to make work in a homenet environment. > > (To be clear, I am just explaining the prefix delegation model.
