[f-nsp] Subnet Question

[Chris Woodfield]

In order to do that you would need to route it to a specific IP  
address in the first block, and your customer would have to have a  
router at that IP address which then connects to the second block.  
Same with assigning a /30; if your switch's IP is .1 and you're  
routing the customer's blocks to .2, the device at the .2 address  
would need to route at layer 3 between tthree networks.

If the customer doesn't have a layer 3 device, then assigning the  
second /29 as a secondary IP is really your only option, but you may  
also want to consider migrating the customer to a larger block, say  
a /28 or /27, and reclaiming the /29. This can be done pretty  
seamlessly with secondary IPs on your switch and his servers; just  
configure the new block alongside the old and have the customer  
change his DNS records when the new block is set up.

HTH,
