3G WWAN HWIC bandwidth aggregation

We are considering using the above cards in a DDR/Dialerwatch backup solution rather than ISDN.

I have read the Q&A on the cards on the Cisco website and it states that multiple cards in the same router can be employed for bandwidth aggregation; however I have also been told that the cards do not support Multilink PPP.

So how do you configure multiple cards to achieve bandwidth aggregation?

Yes, you can use multiple 3G WWAN HWICs in a single router for both backup and bandwidth aggregation. But there is some restriction to configure the 3G Wireless HWIC.

Re: 3G WWAN HWIC bandwidth aggregation

Thanks for your reply. I looked at the document you posted on a number of occasions but cannot see any reference as to HOW you configure the cards to link them together. The document only shows how to use DDR with one card.

Agreed! I'd like to see a config example too. We tried to do multiple nat statements and let cef load-balance them but that didn't work the way we thought it would =/

Thanks!
