We are looking to set up a site-to-site VPN with a backup over a T1. We have a remote site with a 1841 router. This router has a PTP T1 back to a secondary location with a 2811. Due to location, the only option we had to get additional bandwidth was to have a cable modem installed. We want to set a site-to-site up to our primary location, with a backup route over the T1 in the event the cable modem goes down. We have an ASA 5505 at the remote location, and an ASA 5540 at the primary. In addition, we want to split the traffic across the two connections. Since the wireless controllers are anchored back to the secondary location, we want to send that traffic over the PTP T1 and the rest of the traffic over the VPN. We also need to have a backup route for the wireless traffic to send across the VPN in the event the T1 goes down.
