CirrostratusLTM VIP IP range out of self IP range, but still working
I am facing some challenges, when we upgraded to new setup We have single vlan test 1 for VIP's. we configured the self IP 10.40.0.16/255.255.252.0 , which has host range 10.40.0.1 - 10.40.3.254, B...
Ironman,
Virtual Addresses /VIPs dont have to be in the self-IP address space of the VLAN but you would need to have an explicit route to the VIP address from upstream devices to the bigip
Note, the LTM will not send Gratuitous ARPs for such Virtual IPs after going Active - this may cause traffic issues when failover occurs.
So, it's recommended to have the VIP in the same address space but not mandatory.
Hope this helps,

IRONMANThanks, Any reasons we can use like it, VIP not in self ip space?
Do we need route from F5 to upstream devices?
If i use VIP not in self ip space, How it start works after standby f5 become active, without GARP?
