VRRP Configuration (Optional)

In support of load balancing and high-availability functions, the Universal Compute Platform relies on Virtual Router Redundancy Protocol (VRRP) to provide IP abstraction to key functionality. VRRP is critical in the configuration model.

The following operation settings must be defined as part of the VRRP configuration of member nodes:

• Priority— VRRP uses priority settings as a mechanism to arbitrate mastery of the state of exchanges across members of the cluster.
• RouterID — This setting allows segmentation of a routing domain, and it is important to separate from any other VRRP uses on the same network segment. The assigned value is arbitrary, but the value must not overlap when another VRRP usage is visible in the attached network segments.

Note

In a stand-alone configuration, configure priority and router ID with a numeric value. However, in a stand-alone configuration, the specific value is not important. These attribute definitions are important in a multiple-node configuration.
