We have MPLS router connected to a Cisco 4510R switch and also have seperate internet router connected to a firewall and then to the same 4510R switch.
MPLS is used to connect to our datacenter and all internet traffic goes through the firewall to the internet circuit.
I would like to create a IPSec VPN tunnel between this office and datacenter using the firewalls throught the Internet circuit in case MPLS circuit fails.
How do I configure Cisco 4510R to failover between the two routes?
We are using OSPF on this switch and BGP over the MPLS network.
