Cirrostratusvlan as gateway
Hello,
We are creating a new server farm in its own new vlan on our LTM. This should act as the gateway for all servers within the subnet.
Both ltm's in active-standby is connected to our two layer 3 switches.
our experience with ltm is limited, any help to complete the configuration will be great.
vlan25 - 192.168.100.0 /24
On layer 3 switch interface vlan 25 - 192.168.100.1
On ltm :- vlan 25 is created & interface trunked with both layer 3 switch.
ltm1 self ip - 192.168.100.4 & ltm2 self ip - 192.168.100.5
default gateway for servers - 192.168.100.6
1) when we define self ip on ltm1/2 as 192.168.100.4 & 192.168.100.5 , what should be the traffic group ?
2) how to define the floating traffic group on ltm which will server as gateway (192.168.100.6) for the servers in this subnet?
There is a traffic-group already existing, but that is for a different subnet.
Please help.

Non-floating self-IPs are always assigned to traffic-group-local-only

You do not need a new floating traffic group for your new vlan - just use traffic-group-1
As you have an Active-Standby HA group, you want all your floating self-IPs to move if the active device fails, so you only need one floating traffic group. If you wanted an Active-Active or Active-Active-Standby HA group, you need multiple floating traffic groups to distribute some of the traffic to the Active devices (at a minimum, one traffic group per active device).
