[nsp] Bonding multiple ADSL Lines

[Paul Stewart]

Are these ADSL lines using PPPOE?  If so, then you have to bind dialer
interfaces with mlppp as you mentioned.... Have done 4 ISDN channels this
way before and it worked but not sure about limitations...

We have been looking at bonding two ADSL lines for a while for a remote POP
site (dial-up shelves) but haven't actually implemented it.  The nice thing
was that the ADSL was non-PPPOE (ethernet extensions basically) so using CEF
we proved it out that we could just load balance in CEF that same as we do
with T1's currently where needed...

I have a feeling that using dialer interfaces would get messy... Might be
doable though...  And I also heard the CEF can only balance 6 or maybe it
was actually 8 connections at once.. There is a limit, just not sure 100%
what it is...

Hello All,

Trying to put together a couple of working solutions, is is possible to bond
4, 6 and 8 adsl lines together using the 3640's or 26XX range or 37XX
routers. 

Has any-one any experience with this, and if so do you have a recomened
vesion of IOS and memory. 

I'm guessing that physically the 3640 will do this using a combo of
wic-1adsl's and nm-2w and using MLPP to bond them.

I would love to hear your experiences.

Martin.
