I'm working a configuation that will allow us to configure the Cisco 2811 which has an Internet T1 and 3 Point-to-Point T1's strictly data. I need to configure each site but I have several questions and require much help in order to do so. I think I have the scopes completed that I wouldn't mind some review on. Each remote site has DSL as a backup/failover, and I need to know how to configure that into the 1841's. Secondly, they would like to be able to use the DSL if the primary Internet T1 becomes overloaded, I'm not sure if that's possible or not?
Here is the IP Scheme I'm working with:
Site 1-Main Site with Internet T1 and Point-to-Point T1: Using the Cisco 2811 (Cisco2811-SEC/K9), 2 (WIC-1DSU-T1-V2)

Does this look correct? My next problem is that I'm somewhat familiar with the CLI, but not enough, so would it be possible to at least show me one or two of the correct CLI configurations what I would need to implement into the Routers?
Each site needs to be able to communicate with the main site, as well as others. They will be grabbing data from a Windows 2003 Server, DHCP is turned off. There is a Sonic Firewall at each site, configured for DHCP. Is my configuration correct with the Sonic Walls? I'm expecting the LAN IP's at each site to be the above, not the existing.
