I have seen in ISE deployment guide they mentioned two different subnet to have Forwarding VSERVER for PSN node. as shown in below snapshoot:
But if we have ISE PSN node in same subnet as VSERVER how we would achieve forwarding VIP?
I have assign same IP as ISE PSN node on FORWARDING VSERVER and point PSN node to F5 SelfIP it worked, but when I restart PSN it wouldn't comeup since it tries to check if there is an existing IP in the network?
Are you trying to forward traffic from the left side to the ISE-PSN servers? For example, the ISE-PAN-1 needs to talk directly to 10.1.99.5? If so, then you would configure a virtual server of type Forwarding (IP) that would have the address 10.1.99.0/24. You would probably want to enable it only on the VLAN98.
