APAR Error Description / Circumvention

-----------------------------------------------
Locally initiated connections that select a Virtual IP Address
(VIPA) as the source address may use a different outbound
connection than remotely initiated connections with that same
VIPA source address.

CORRECTION FOR APAR MA43374 :
-----------------------------
If the local address is a VIPA using proxy ARP, outbound route
selection should prefer a route bound to the VIPA's proxy agent
interface. This increases the likelihood that inbound and
outbound traffic for a VIPA will use the same interface as is
the case for physical interfaces.

This route selection logic has been the case for remotely
initiated connections or locally initiated connections that
explicitly bind to the VIPA as the source address. This change
provides the same preference for locally initiated connections
when the system selects a VIPA as the source address.

CIRCUMVENTION FOR APAR MA43374 :
--------------------------------
None.
