Ya,
'dialer load-threshold' sets the threshold for bringing up additional links, bu
t each remains a discrete link. Any load balancing of traffic across the links
is subject to normal IOS route-caching rules (on=per destination, off=per packe
t). Load balancing at layer-3, if you will.
'ppp multilink' provides options on how to handle ppp encapsulated traffic, inc
luding a means to mux traffic across the two (or more) physical links as if the
y were one "virtual" pipe (fragmentation). Load balancing at layer-2, if you wi
ll. It also provides a means to control the way the traffic is "striped" across
the links (interleaving and fragment-delay), which can prove useful when you a
re trying to share bandwidth between traffic with significantly differing packe
t sizes and delay sensitivities (say FTP and voice).
Regards,
Mas Kato
