Can anybody give me advice on IP fail-over?
In the diagram provided below I show a simple layout of what I intend to do.
What I need is advice about the following
1)A quick briefing on how IP fail-over would work in this scenario
2)Configuration & concepts
The Data Centre has a Cisco ASA firewall
The Primary line is a 100Mbps leased line
The Backup/fail-over Line is the an SDSL Line
All VPN's will terminate on the ASA firewall
I'm struggling to find any links on IP fail over or examples of set-ups
If you need any more detail please let me know
PS I have purposely left out any IP info as the HQ is going to be a new office and there is nothing set-up there in terms of equipment and IP addresses, so this is essentially a "Clean slate design"
