We have IPSec VPN connectivity to our clients as our primary link and now we are also planing to setup DR over VPN however I cant figure out how to configure client site routers, because of financial issues we have to use the same router on client site for production and DR. We do not run any routing protocol with client (all Static).
The issues I have
1) how to setup 2 separate tunnels on the same routers for the same traffic (source and destination will remain same)
2) The DR tunnel should not come up as long as the primary connection is good.
