We have a couple of branch offices that need to connect to a main site. We plan to use Cisco ASAs 5515 to establish VPN connections. We would also like to have 2 ISPs at each location to make the connection redundant. Here is the image:
I am a bit new to ASAs so far, so my question is "Is it possible to set up ASA 5515 to use 2 ISPs to have VPN connection with a remote site and in case of the main ISP's failure switch over to backup ISP automatically and then to return back to the main one when the link is reestablished ?"
