Hello,
We have a situation where we are comissioning a DR site. We have three tunnel interfaces for our three remote sites and a loopback interface for crypto maps at the headoffice on a ciso 3845.the config is as followed.
As per my initial analysis loopback interfaces and GRE tunnels are not supported on the ASA firewall
We dont have a router on our DR site what we have is a ASA 5510, now i need to make sure that i have a solution to accomodate GRE tunnel and loopback interface without procuring a router.
