APAR Error Description / Circumvention

-----------------------------------------------
After upgrading from V6R1 to V7R1, PPP dial on demand (DOD),
does NOT happen with FTP.

CORRECTION FOR APAR MA40053 :
-----------------------------
When attempting to connect, a route must be selected. During
this process, the source IP address for the connection is
selected or validated. This source IP address validation
incorrectly rejected the PPP Dial-on-demand interface's source
IP address, causing the connection attempt to fail before it had
a chance to initiate the PPP interface dial. This has now been
corrected.

CIRCUMVENTION FOR APAR MA40053 :
--------------------------------
A PPP profile can be configured as either a "numbered" interface
where the profile has a unique local IP address or as an
"unnumbered" interface where multiple profiles share a local IP
address that is separately configured as a Virtual IP address or
as a local LAN interface address. This error only occurs when
using a numbered interface. Reconfiguring the PPP profile to use
an unnumbered interface will avoid the problem.
