I am new to ASA configuration and I need some advice.
I have an ASA IPSEC VPN Hub and Spoke configuration with fixed IP@ (outside) on the central ASA and dynamic IP@ on the spokes.
I have now a new ISP link connected to my central ASA (new interface let's say outside2) and I'd like to migrate some L2L VPN links to that new interface 'outside2', whereas some remain on the other interface 'outside'.
Is that possible ?
I can't understand what to do with the routes. The central ASA can only have one default route but how is it aware of the public IP@ of the spokes in order to establish the tunnel via outside or outside2 interface ?
Thanks for your help
