Does anyone know if you can prevent the load sharing for outbound
network traffic when using IPMP? I have some application people who say
this is causing some problems Inbound is easy by just using the IP, but
outbound can use two interfaces/IPs.

Thank you!

The easiest way I believe is: dont use probe based IPMP.
You give up the pings, use fewer addresses, and you get a warning
during a reboot
but otherwise things seem to work the same for failover and its dead
simple to set up.
Another way is to dicker with the ifconfig flags but Ive never tried
that.

it does not detect failing switch or router, just failing links.

the interfaces with the probe adresses must marked as deprecated and
-failover and should not used by applications. Deprecated means here if
a software opens a socket without an explicit ip, this interfaces are
not used by solaris, as far as i remember.

man ifconfig:
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. See INTERFACE
FLAGS for information on the flags supported by ifconfig.
