I've tried searching for some of this information but haven't really found a good answer.
From what I've found, VLAN's require an IP, but I haven't found anything saying if it can be just a floating IP, or if you have to have a static IP as well? And are you able to set multiple floating IP's? If so, what is the maximum?
I don't see why you couldn't but why you need to set multiple self IP or floating IP? everything depends what you want to do.
case3 (cluster) - Active - Standby:
case4 (cluster) - Active - Active:
- Multiple statique self-IP on the same VLAN with different subnet...
tell me exactly what you want to do and I can help you.
you can assign as much floating IP as your VLAN/subnet allows. But don't forget that you have an restriction about datagroup creation for activ activ infra.
Does adding extra floating IP's provide any benefit? Will the F5 spread the traffic over the floating IP's in that VLAN?
the creation of several floatingIP will allow you to deploy an active active infra and thus mastered the outgoing flow by DG.
If you want to spread traffic over multiple IP you have to use snat pool. it is sometimes useful when you reach the 64000 outgoing connection..
Not sure if this answers your question, but you have to have a single non-floating IP per VLAN.
If you use High Availability, you can add Floating IP's as well, and they are used as cluster IP's, much like Cisco HSRP.
Thank you! That does answer my question! Do you happen to know also how many floating IP's you can assign per VLAN?
A self-ip is for each individual device to communicate from in each VLAN. A floating IP "floats" to the active unit.
HERE is a good DevCentral post on the topic, and HERE is some F5 documentation on the topic!
Hope that helps! If it does please up-vote and select this answer, it would be greatly appreciated!
