Chapter 9 System Redundancy : Redundancy Priority Level Definitions

Redundancy Priority Level Definitions
A number of TIBCO Messaging Appliance P-7500 priority levels have been defined for redundancy. These priority levels are advertised by the virtual routers.
When activity switches occur between redundant pairs, the priority levels advertised by the virtual routers of each system change to indicate their current state and role. These advertisements are broadcast between redundant pairs through VRRP. For example, the virtual router that advertises the highest priority level for a given VRID is the active virtual router for that VRID. All messages and system requests for that VRID are then forwarded to that virtual router.
For more information on the advertised local priority levels and how to monitor current priority levels, refer to “Monitoring Redundancy” on page  169.
