Hello,

 in fact on the network side there are no troubles I have done similar
things during migration (IP is layer 3 VLAN is layer 2) ;-)

But what I am looking for is a clue on secondary IP support on sun systems.

example :

A is in sub SA
B is in sub SA
A and B access to C in sub SA

A B C are in VLAN V1

I want to change IP subnet SA to SB :

migration :
C listen on SA and SB on VLAN V1
B change of sub SA to SB
Test to see if B and A are accessing C

A change of sub SA to SB
Test to see if B and A are accessing C
Then delete IP addresses from SA on C

> Hello,

I am looking for a solution to put 2 IP adresses of 2 different subnet on
the same physical interface :

etc/hostname.ce0
192.168.0.1 netmask + broadcast + up
addif 10.0.0.1 netmask + broadcast + up

Is this going to work ?

If yes can I do something like :

*/etc/hostname.ce0*

*192.178.1.119 netmask + broadcast + group prod -failover deprecated up*

*addif* 192.178.1.120 netmask + broadcast + up

addif 192.178.1.121* netmask + broadcast + up*

*addif 10.98.7.224 netmask + broadcast + group prod2 -failover deprecated up
*

*addif 10.98.7.220 netmask + broadcast + up*

*addif 10.98.7.222 netmask + broadcast + up*

**

*/etc/hostname.qfe0*

*192.178.1.78 netmask + broadcast + group prod -failover deprecated standby
up*

*addif 10.98.7.226 netmask + broadcast + group prod2 -failover deprecated
standby up*

**

*Thanks !*
