Multiple-SLB-Group Configuration

Language:

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 server's 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.
