Chapter 10. Configuring the LVS Routers with Piranha Configuration Tool
Figure 10-3. The GLOBAL SETTINGS Panel
The top half of this panel sets up the primary LVS router's public and private network in-
terfaces. These are the interfaces already configured in Section 9.1.1 Configuring Network
Interfaces for a NAT LVS Cluster.
Primary server public IP
In this field, enter the publicly routable real IP address for the primary LVS node.
Primary server private IP
Enter the real IP address for an alternative network interface on the primary LVS
node. This address is used solely as an alternative heartbeat channel for the backup
router and does not have to correlate to the real private IP address assigned in Section
9.1.1 Configuring Network Interfaces for a NAT LVS Cluster. You may leave this field
blank, but doing so will mean there is no alternate heartbeat channel for the backup
LVS router to use and therefore will create a single point of failure.
