Radware Alteon Application Manual page 529

In this configuration, when both devices are healthy, the load-balanced packets are sent to the
virtual server IP address (205.178.13.226 in
resulting in higher capacity and performance than when the devices are used in an active-standby
configuration.
The Alteon device on which a frame enters the virtual server router is the one that processes that
frame. The ingress device is determined by external factors, such as routing and STP settings.
Note: Each VRRP-capable device is autonomous. There is no requirement that the devices in a
virtual router be identically configured. Different Alteon models with different numbers of ports and
different enabled services may be used in a virtual router.
Configuring Active-Active Redundancy
Perform the following steps on both the active and the standby Alteon:
1. Configure the appropriate Layer 2 and Layer 3 parameters on both devices.
This configuration includes any required VLANs, IP interfaces, default gateways, and so on. If IP
interfaces are configured, none of them should use the VIP address described in
more information, see
2. Define all filters required for your network configuration. Filters may be configured on one
device and synchronized with the settings on the other device (see
3. Configure all required SLB parameters on one of the devices. For the purposes of this example,
assume that Alteon 1 is configured in this step. Configure a VIP set to 205.178.13.226, and one
real server group with two real servers:
RIP 10.10.10.103 should be configured as a backup server to RIP 10.10.10.101.
RIP 10.10.10.104 should be configured as a backup server to RIP 10.10.10.102.
Note: In this configuration, each server's backup is attached to the other device. This ensures
that operation continues if all of the servers attached to a device fail.

4. Configure the VRRP parameters on the device, as follows:
— Set the VRID set to 2.
— Set the VIP address to 205.178.13.226
— Set the priority to 101.
— Enable sharing.
For more information, see
5. Configure virtual router redundancy:
— Disable synchronization of VRRP priority to Alteon 2. Use the
command. This leaves Alteon 2 with its default priority of 100.
— Synchronize the SLB and VRRP configurations by pushing the configuration from Alteon 1 to
Alteon 2. Use the
For more information, see
6. Reverse the roles of the real servers and their backups in Alteon 2's configuration:
RIP 10.10.10.101 should be configured as a backup server to RIP 10.10.10.103.
RIP 10.10.10.102 should be configured as a backup server to RIP 10.10.10.104.
