Hi,
-
Do we need to let the IP of those servers to be the same IP?
No, Its not necessary to have same range IP address for servers. You just need to use SNAT/Automap and your problem will be resolved.
2, Does this mean, the VIrtual Server IP we will use is same between two sites right, and the pool members are the servers from site a and site b?
Virtual IP will be same as user's will hit single IP address (Virtual server ip) and then to pool member.Below is the traffic flow:- User hit URL--> DNS to IP-->VIP/VS---> SNAT-->POOL--->Pool Member(Site A server in active state and site B in standby state)
- does two f5 for each site applicable?
No, only one F5 will work here after using "Priority Group Activation" in Pool member will be in Active standby mode.
