Hi,
Actually We have Two Site and 3 HA For cisco Firewall
1. Location has --
FTD2110 With ASA Image - HA
FTD 2110 with FTD image - HA
2. Location Has
FTD 2130 With FTD Image HA
we have ISE for both Location
and Duo For Both Location
Now we need Redudancy for ISE from Cisco Anyconnect
So for 1st location - suppose ISE for 1st location will be down so user can be authenticated from second location
In this case what configuration we should do in cisco Firewall
Actually we should give 2 radius server(ISE ) For authentication
But we need automatic fail over
How can we achieve this ?
