I agree,
dialer load-threshold has to be used in order to bound or bring up
individual bri links based on traffic load.
Original question:
My understanding is that when you use dialer load-threshold independently of
the ppp multilink (w/o ppp multilink) is when u have multiple bri interfaces
in a rotary group and you want to bound (mux) all of you individual bri's
together to have more bandwidth (more than 128k) for traffic going to the
dialed site. Using dialer load-threshold 1 or 2 keeps the traffic bound
together indefinitely and if available will add more circuits (56k/64k
bandwidth) to the pipe based on the load of the traffic.
See:

Any other views. Haven't seen this highly used but based on reading can be
done.

Greetings Ya,
How's the weather on the other side of the planet? Is it true that water
spins clockwise down the drain?
Anyway... In my understanding the only thing that PPP multilink does
differently than not using it is allow packets to be split and sequenced
across two or more connections that form the multilink bundle. If you did
not use it then it would be like having two routing paths to same
destination in which case the load is balanced across the two. In either
case, the only way to bring up a 2nd link is the "dialer load-threshold"
command which you mentioned. If anyone has been able to bring up 2nd
without the "dialer load-threshold" I would like to know how.
Later
GW

Hi all,
I have a concept problem with PPP Multilink in BRI Interface.
Cisco Documentation states:
1) Don't have to use "PPP Multilink" to bring up the second BRI link when
needed, only "dialer load-threshold <n>" command is enough to do that, and
in this case we have to use "bandwidth" command to specify the interface
bandwidth so that Load-threshold can cancalculate the load on the first link
before bringing up the second one.
2) If we use "PPP Multilink" command, "dialer load-threshold 1 " command can
no longer bring up both links
My findings contradict all that.
No difference between configuring "PPP Multilink" or not, I can still bring
up the other link by only using "dialer load-threshold <n>"
I must be missing the point, can any body share views on this one.
Appreciate your help in advance.
Cheers from beautiful Sydney
Ya
