Redundancy without touching existing network

Hello,

I have a customer that has requested a proposal to add redundancy to their network as part of a business continuity plan.

Currently their main office is connected to seven sales offices through a managed VPN provided by their parent company.  Their parent company will not place a second line in each location in order to provide failover (I know it's crazy), so they are looking elsewhere.

The catch is that the managed VPN section of the network (that is, the routers and everything in between) cannot be changed or touched.  It even may be impossible to get configurations of the routers involved.

I was toying around with the idea of placing an extra line & router in each location, plus an additional routing device behind (that is, on the LAN side) the two internet/VPN facing routers, then possibly using tracking to switch from one network to the other... but without knowing what is going on in the managed VPN in place, I am worried about routing issues etc.

Any options out there?

Thanks,

Al

Redundancy without touching existing network

This can be done in different ways however without having an idea about the current config and doing some minor chanes to it it will be a high risk and even it may not work at all and break the current communication

Hope this help
