We have used both, and have found that MLPPP gives better results for real-time applications like voice at the cost of increased CPU. For generic data links, ip load-sharing per packet works fine. If the source and destination traffic is reasonably diverse, simple equal cost routes without per-packet will work as well, but you won't get greater than 1.5mbps for a given flow. > > I've got what seems to me like an innocuous question for this list... > > > > Someone is requesting access to about 3 mb of traffic up/dn.
