Bonding with Cisco IOS

After a few nights of meddling with my configuration, the following setup is working well for me. I would like to share it with the community.

Perquisites

Ask support for a unique IP address for the dialer interface of each of your ADSL lines
You will also need a static block for your routing IP address and any external clients, you may also use one of these addresses for NAT (more on that later).
Configure Clueless to route your static block down each of the ADSL lines

My Setup

Three ADSL lines provided by AAISP
Cisco 2821 running IOS 15.1
Three WIC1-ADSL and an NM-ESW-16 switch module.
Internal ADSL interfaces allow me to run the setup in PPPoA mode. Modify your dialers for PPPoE if you are using external bridges.
