The config works - just don't think it is optimal. I structured it based on the mpd5.conf.sample and some other configurations stolen from dslreports.com. I am looking more for advised MRU/MTU, and MRRU values for the links and the bundle as a whole as I do not believe my settings are optimal. I have tested a 2link configuration with similar values and obtained very, very fast speeds. Adding the 3rd link with the settings below does improve the speed, but I do not feel it is as fast as it should be.

Not my area of best knowledge but a couple of points.. Use 'load' to abstract away common items from the links Try not to reference things until after they are defined.. is this working? and if not, what happens?
