Forcing Solaris 10 IPMP traffic on one NIC only

[Database Administrator]

To whom it may concern,

We are running IPMP at our Solaris 10 server. The primary address is
172.28.134.149 and
2 payload addresses are 172.28.134.142 and 172.28.134.143. We notice
that our traffic from an appication to another server is going thru
the payload address172.28.134.142 and not the primary address.

Is there any way for an application to be "forced" to use the primary
address 172.28.134.149
exclusively and not thru other 2 non-primary NICs ?

Thanks, Bill

Add the "deprecated" flag to the interfaces in question. From the
ifconfig man page:

deprecated

Marks the logical interface as deprecated. An address associated
with a deprecated interface will not be used as source address for
outbound packets unless either there are no other addresses
available on the interface or the application has bound to this
address explicitly. The status display shows DEPRECATED as part of
flags.

an application can bind to a specific address and must not use *, but
the deprecated flag is what you look for i assume.
