Dave,

In this context, load balancing means the interface will try to distribute
traffic across both circuits such that each circuit is carrying the same
volume of traffic regardless of packet arrival sequence or destination?

IOW, if dialer-threshold is configured to kick in when the first circuit
reaches 50% (or 32k), then once the 2nd circuit is brought up, assuming the
traffic load remains the same, each circuit will carry 16k worth of traffic?

TIA, Tim

Dave,

This is on load, not per packet.

It could have taken 50 packets to push it up to the configured load, or only
30, depending on what type of packets are going across the link.

Scott,

"If you want to do L3 load balancing, then you'll run dialer load-threshold
WITHOUT running multilink."

So, configuring "dialer load-threshold" without "ppp multilink" is a method
of layer 3 load balancing over two B channels? Would this be per-packet load
balancing?

TIA,
DAve
