I'm not sure this will help you but we run multiple VLANs thru a single
vswitch. We define our cisco router port to the OSA as a vlan trunk
defining the default gateway for each of our zVM linux VLANs. Our
vswitch is defined as VLAN unaware so all the VLAN s forward traffic up
the trunk to each VLA
I have always coded routes and masks within the GATEWAY based on the class
represented by the network address. 10 is a class A address so to code subnet

10 = LCS0 1492 0.255.255.0 10.0.0.

Do you really mean what you say or do you have terminology mixed up?
VLAN is the technique to tag packets with a VLAN ID.
I will be converting a SLES9 zVM guest lan guest to VLAN in the near future and
I was wondering if there are any specific steps I need to do to change the
definitions. I tried cloning a SLES9 guest lan master to a VLAN host a while
