VRRP Configuration (Optional)

The Universal Compute Platform relies on Virtual Router Redundancy Protocol (VRRP) to provide IP abstraction to key functionality.

Some applications request that you configure a VRRP address for access to that application's management interface. VRRP can be used to configure an IP alias with pass-through capability for the Universal Compute Platform data interface to that application's management interface.

If you are using VRRP, the following settings must be defined for the VRRP configuration on a data port:

Address—You can assign up to ten VRRP IP addresses for a single data port. Note the following:
- VRRP IPs must be within the same segment as configured for the interface.
- VRRP IP addresses must not overlap with any other address in use in the segment, including addresses that are assigned by the application.
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.
