CSM Loadbalancing multiple server VLANs

[joemarr_brodart]

Is it possible to loadbalance servers located in multiple VLANs using the CSM? I have a need to loadbalance sites the may be located in different VLANs/Subnets but I am unable to consolidate them into a single subnet.

Its possible.

Just make sure that return traffic from Real Servers should not bypass CSM.

This can be achieved by using one of the three methods.

1. By configuring CSM's server Vlan IP as the Default Gateway on Real Servers.

Or

2. Using Source NAT on CSM.

Or

3. Using PBR

Due to the need for these server to communicate as themselves for non-load balanced traffic, I would need to go with PBR or SNAT and have the CSM configured in a One-Arm config, correct?

I should clarify, what if the second or third server is in a 6500 that is adjacent to the 6500 that has the CSM and there is no trunk to carry the VLAN traffic? The only access to the VLAN is via layer 3. Will the CSM still use this server as part of the server farm?
