C H A P T E R 6 SA8250 Scenarios

Scenario 2:
Load
Balancing
Servers with
Source
Address
Preservation
In its default operating mode, the SA8250 alters source and
destination packet addresses so that fulfillment servers see only the
SA8250’s address. However, under some circumstances,
administrators may want to preserve incoming clients’ addresses in
the server log files.
The SA8250’s Source Address Preservation (SAP) mode ensures that
a client’s address remains as the source address of packets forwarded
to the server, thus ensuring the maintenance of a record of client
addresses in the server logs. This scenario illustrates the steps
required to enable Source Address Preservation and configure the
SA8250 to broadcast routes.
