#### Multiple-SLB-Group Configuration

This example shows the SLB configuration with servers configured as multiple SLB groups. Servers and clients are at multiple VLANs, and the servers are indirectly attached to the switch.

Feature | Default Settings
--- | ---
VIP of SLB group 1 | `10.10.10.1`
Active servers’ RIP | `192.0.0.1`, `192.0.0.2`, `192.0.0.3`
Standby servers’ RIP | `192.0.0.4`
VIP of SLB group 2 | `11.11.11.1`
Active servers’ RIP | `192.1.0.1`, `192.1.0.2`, `192.1.0.3`
Client subnet | `20.0.0.0`/`24`
Client VLAN | `VLAN 2`
Server SLB group 1 Subnet | `192.0.0.0`/`24`
Server SLB group 1 Subnet interface address | `192.0.0.100`
Server SLB group 1 VLAN | `VLAN 3`
Server SLB group 2 subnet | `192.1.0.0`/`24`
Server SLB group 2 subnet interface address | `192.1.0.100`
Server SLB group 2 VLAN | `VLAN 4`
Network interface for both servers | `ixgbe0`

In this sample configuration, the switches perform as follows:

Switch A:

- Runs SLB.

- Attached to the client network using switch ports extreme-ethernet 0/1-4.

- Connected to switch B through two uplink ports extreme-ethernet 0/9-10. Port extreme-ethernet 0/9 carries `VLAN 3` traffic, port extreme-ethernet 0/10 carries `VLAN 4` traffic.

Switch B:

- Directly connects to the servers.

- Connects to switch A through two uplink ports extreme-ethernet 0/11-12. Port extreme-ethernet 0/11 carries `VLAN 3` traffic, port extreme-ethernet 0/12 carries `VLAN 4` traffic.

- Servers in SLB group1 are connected to switch ports extreme-ethernet 0/15-18.

- Servers in SLB group 2 are connected to switch ports extreme-ethernet 0/19-21.
