ASA/PIX Redundant Tunnels with Separate Interfaces and ISPs?
I have an ASA5510 at location 1, and a PIX at location 2. Location #2's PIX is on a multihomed BGP routing setup, so it's primarily covered for any issues.
Location 1 has 2 internet lines but each is routed independently and thus not multihomed. Can I take the ASA5510 and define 2 interfaces, one to each ISP, and designate one as the backup? Both would talk back to the Site #2 PIX. Is it possible to apply a crypto map like this? How do I deal with default gateway routing issues?
