GW,

That's true, water here spins anticlockwise if you fill up the sink and then
unplug the drain..funny isn't it.

I didn't follow exactely your point, do you mean to say:

1) If we use "PPP Multilink" there will be no equal bandwidth distribution
between both B channels when both of them are up?

2) While if we skip "PPP Multilink" from config, traffic will be equally
distributed among both B channels?

Or was it the other way around.

Cheers
Ya

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
