NimbostratusF5 LTM creating VLANs etc
I have a VLAN SVI (VLAN5) on our cores. I created another VLAN (VLAN6) in the database which will be the virtual servers for VLAN5.
So basically users can hit the IP from VLAN6 which then will ...

NimbostratusIn terms of routing, it is not recommended to have the same HA/Floating IP on your switch infrastructure and your LTM. In the switching realm, you would create the HSRP environment (Vlan 5) on your distribution-pair switch (common setup) but you would not create another SVI for the same vlan (Vlan 5) on another L3 switch. In the same sense, you would not create a Vlan 5 interface on your LTM. Hence, why Vlan 6 works but Vlan 5 does not. Especially since they are all in the same L3 routing domain.
You can perform L2 pass thru routing from your HSRP config to the LTM without having the forwarding/L4/vlan setup on your LTM. But is it considered "best practice"? Im not sure on that one. Overall, if you were to perform the L2 pass thru method... insure that V5 is routed down to your LTM "transit" global forwarding-IP.
