Hi!
I'm using multipathnig on my Solaris 9. I have two network interfaces connected to the same network (having two different IPs) and I also have a virtual IP addres bind to one of these interfaces. What I would like to do is to set the src ip of the outgoing packages to this virtual IP.
Is there any way to do this?
Thanks.
In a normal IPMP configuration, the non-virtual addresses are marked as deprecated. That prevents them from being used as a source address. So only the virtual will be selected for that.
# man ifconfig
[snip]
deprecated
Marks the address as a deprecated address. Addresses
marked as deprecated will not be used as source
address for outbound packets unless either there are
no other addresses available on this interface or the
application has bound to this address explicitly. The
status display shows DEPRECATED as part of flags.
However, you've not shown your IPMP configuration, nor have you shown the running network configuration, so I'm only guessing.

What I would like to achive is that all outgoing packages on interface ce0 and ce2 should have as source IP the address fro ce0:2 (10.211.4.211)
Okay.
I'm assuming ce0:1 and ce2:1 are your test addresses.
ce0 and ce2 are both in 'linkA'. Outbound packets may use either address. Both will be available as failover if either ce0 or ce2 fails.
However, what is ce0:2 doing? It's not part of your IPMP but it is on the same subnet. It is not protected against failure of ce0 and may be used for outbound traffic. Why is it configured?
Also, do you have your /etc/netmasks file set properly? Both ce0 and ce2 have different netmasks from the others.

My netmask file looks ok:
10.211.4.17255.255.255.0
10.211.4.19255.255.255.0
ce0:2 is an ip managed by a third party software ( veritas cluster server) The application that configures ce0:2 checks the mpath daemon and in case of failover to ce2 it moves the ce0:2 to ce2:2.
Basically I have a cluster install and the cluster server in case of failover from a node to the other moves the IP address from the ce0:2 to the active node. What I want is that whichever is the active node the outgoing packets source ip should be the address from ce0:2
