I need help with a design for a customer. We are looking to provide site-to-site VPNs with C85x Series at the remote sites and a redundant pair of ASA?s at the central site.
The complication is that the customer wishes to have resilient internet links at the central site; these two links which each have different public IPs. Should either link fail the VPN?s must work via the other link.
Is this configuration possible and if so how can it be done?
Any help or experience you may have would be appreciated.
