Real servers in different subnets

Hi ,

Is it possible to load balance real server across the VLANs, I have requirement to load balance two servers which are in two different subnets. Can anyone confirm that it is possible and there are no known issues in that? Here is the script for my config

rserver host rsrv1
ip address 172.16.10.10
inservice
rserver host rsrv2
ip address 172.17.10.10
inservice

serverfarm host farm-demo
rserver rsrv1
inservice
rserver rsrv2
inservice

class-map match-any VIP
2 match virtual-address 172.16.100.100 eq 80

policy-map type loadbalance first-match server-balance
class class-default
serverfarm farm-demo

policy-map multi-match client-side
class VIP
    loadbalance vip inservice
    loadbalance policy server-balance
    loadbalance vip icmp-reply active

interface vlan 20
description side-server
ip address 172.16.10.10 255.255.255.0
service-policy input client-side
no shutdown
interface vlan 30
description side-server
ip address 172.17.10.10 255.255.255.0
service-policy input client-side
no shutdown

interface vlan 10
description side-client
ip address 172.16.100.10 255.255.255.0
service-policy input client-side
no shutdown

ip route 0.0.0.0 0.0.0.0 172.16.100.1 (SVI Core)

Thnx

Hi Aslam,

It shouldn't be a problem.

Just make sure the reply from the server is hitting the ACE on the same interface the request came out from (It should be the case in your setup since both of your rservers seems to be on directly connected networks and I guess they have ACE as DGW).

Regards,

Nicolas
