It seems ft groups are the ACE redundancy feature. FT groups are associated with contexts. In turn contexts are associated with slb groups. Does this mean, one must group slb groups into contexts according to failover behavior?
In other words, how do I relate contexts, ft groups and slb groups? I need some to be Active-Active and some Active-Standby.
yes you need ot buy a license if you want more than 5 contexts.
The client should target the vip - vserver address unless this address is not part of a vlan. In this case a static route on the gateway for the vip should be configured and you point the next-hop to be the interface alias address.
The FT addresses are only being used by ACE itself.
