Cisco 2801 mpls to adsl failover

Hi, I have a remote site (Cisco 2801) connected via a 512kbps MPLS leased line to its parent site router (Cisco 2811).

There is a 2mb ADSL line already inplace (connected via a Cisco 800) at the remote site which is used for a wireless network to access the web. I want to make use of this line as a failover in the event of the MPLS going down. It would also need to automaticlly route snmp \ smtp traffic as well as SMB \ Http data. The wireless network must not be able to see the 2801 network, but the 2801 needs to be able to access the Wireless network for management purposes.

Can anyone suggest the neccesary harwdare to add to the 2801 as well as point me in the right direction for configuring it? I'm already looking at GLBP on Cisco's website.

How are these all linked together? Via switch or just daisy changed? I take it a separate wireless access point is connected to the 800 or is it a 'w' model with built-in wireless?

Depending on how you have things connected, you'd probably be best of running HSRP to provide the first-hop redundancy and place the wireless clients on a separate VLAN, denying that VLAN access to sensitive equipment.

The wlan is structured as follows: Client (roughly 100 per site) to Cisco AP (about 10 per site) to via cat 5 to HP switch. from there via Fibre cable to parent switch connetcing to Cisco 800, which then plugs into ADSL line.

Corporate network is connected as follows: Server \ Clients connected to HP switch, linked to Cisco 2801 router linked to MPLS leased line back to head office.

At present both networks are totally seperate which is a pain when I want to configure something. One thought would be to replace the Cisco 800 with another 2801. This would have an ADSL WIC installed plus an additional serial interface I could connect to the Corporate 2801.

Is the parent switch and corporate HP switch within cabling distance of each other?

yes they are right next to one another. If we patch them together both systems can see one another so a Vlan is one possible solution here.
