Chapter 14 Load Balancing in the P333R-LB
Avaya P333R-LB User’s Guide 57
Policy-Based Routing (Source-Based Routing)
Using AR rules, you can configure your device to support Policy-Based Routing
according to the client IP. In this case, you can select your next Hop according to the
source IP configured on your device.
Selecting a Load Balancing Metric and Persistency Option
The different load balancing metrics and persistency options provide you with the
following flexibility:
• Round Robin generally gives you the best load balancing solution.
• MinMiss Hash with the key set to Source IP gives the best persistency, without
using the persistency cache.
• The persistency cache mechanism enables you to specify the required client
persistency time.
• The wildcard feature allows the client to maintain persistency when the same
client is mapped to a different IP address by a NAT device. However,
persistency cache size is limited, and it somewhat increases the session
processing overhead.
