vlan

I would like to establish the setup shown below. The image is taken from (http://gcharriere.com/blog/?p=620) and explains how to set this up on a brocade device.

I would like to use an ubuntu server to do the routing. Right now, the switch and the server/router are connected with a trunk and the server uses the vlan package, kernel module and (inner) subnets for routing. I would like that:

no IP addresses get lost in the subnetting (outer subnet is /26, inner subnets are /28)
I don't want the rigorous subdivision of my outer subnet. I want to assign a VLAN to any IP in the outer subnet.

How do I need to configure my interfaces? What is the "ubuntu" translation of "ip follow ve"?

Thanks!
