So if only one dial map existed and you used "load-threshold", would it
bring up another BRI and put every other PPP frame onto each of the 2
BRI's?

Or would you need 2 dial maps?

If you use PPP multilink, then is it best to use the same generic
"load-threshold" command or the PPP multilink version of the command?
I would think that PPP multilink puts traffic accross the links in some
very low level or bit level load balancing. Is that the difference
between using "load-threshold" without multilink and "PPP multilink"?
