Application Redirection Configuration Overview
Configuring Avaya P330 Load Balancing Manager for AR involves
several steps. This section provides an overview of the entire process,
and the following sections explain each step in detail.
To configure Avaya P330 Load Balancing Manager to perform
Application Redirection:
1. Configure VLAN Area Mapping
2. Define one or more services (refer to “Defining a Service” on
page 55).
3. Define one or more RSGs and RSs for each service (refer to
“Defining RSGs and RSs for Application Redirection” on page 56).
4. Define one or more rules for each service (refer to “Defining a
Rule” on page 56).
After you define a new AR element, click
Send to Device
to apply the
configuration changes to the device. To save the configuration changes,
click
Commit
. For more information about applying and saving changes,
refer to “Saving Configuration Changes” on page 24.
VLAN Area Mapping
In the Application Redirection packet flow, there are two events that are
indistinguishable on the IP level:
• When a session arrives from the client, the session should be
redirected to the RS.
• When a session arrives from the RS with the same addresses, the
session should be routed to the ultimate destination.
To address this issue, the load balancer uses different VLAN areas for the
clients and the RS. If a session arrives at the load balancer from the
clients’ VLAN, it is redirected to the RS. If a packet arrives from the RS’s
VLAN, it is routed to the ultimate destination.
