VPN tunnel for failover

[kunz12]

Hello All -

We have about 8 different plant locations that are connected to the corp using a MPLS cloud. Each one of the plant locations have a backup DSL line in case the connection to the MPLS goes down. I will be configuring a site-2-site IPSEC VPN tunnel between each plant and the corp using the backup DSL line.

My question is, after I create the tunnel to the corp, how should I configure routing on the router so that the traffic is automatically routed over the VPN if the MPLS connection goes down.

Using BGP as the routing protocol over the MPLS.

Thanks for your help!

This is a time to use IPSEC GRE tunnels. This way you can extend your routing protocols over to the VPN, even use it for non critical traffic all the time and take the load off of the high dollar leased line. Here is an example from cisco

let me know if you need more.
