Here is the situation:
MPLS network between corporate office and 5 branch sites.
Branch sites each have a cisco 2600 which connects them to the MPLS, and thus back to corporate office for all network/internet access. ( I am pretty sure each router has an empty slot for a WIC)
Corporate has a T1 connected to PIX515 (6.3(4)) providing internet access for entire company.
I would like to have a DSL connection at each branch office to act as a backup in case the MPLS goes down.
The DSL would VPN back to the PIX at corporate.
Ideallly all branch network traffic would still come back through corporate, but the bottom line is to ensure each branch can still get to our corporate network if the MPLS goes down... Of course the failover would need to be automatic.
FYI- the pix is currently providing PPTP client access (XP Native VPN client), and Cisco VPN Client access, in addition to the normal PIX duties...
