Has anyone worked up a guide to configuring VPN failover from WAN 1 to WAN 2 where the other end is an ASA? On the MX the configuration should be trivial, but on the ASA side it might be a bit more involved. Haven't found anything here or in the Cisco Community on the topic that goes into specifics.
Also, does the MX support stateful failover for VPN traffic going to third party endpoints? For example, would TCP sessions and NAT translations be capable of being immediately reassigned to the VPN tunnel on WAN 2, without the need for the endpoints to restart whatever sessions they're running?
