I have seen this question from time to time (myself included) so you're not alone in your thinking here. The short answer is that the network should be private, and by advertising it in OSPF, any traffic sent to the network will end up having a NAT'd response, causing unwanted issues (or something like that)
In all honesty, I'm not sure if you would lose points here or not, will leave that for Tyson or Marko HTH Thank you.

The DSG shows the OSPF process being modified to no longer advertise the route of the natted network. I understand the thought process behind that, but it doesn't seem necesary to meet the requirements of the task. I'm trying to stick to the idea that if it's not called for then I'm not going to make any additional changes. I was just wondering if maybe I was missing something. _______________________________________________ For more information regarding industry leading CCIE Lab training, please visit www.ipexpert.com UHS Confidentiality Notice: This e-mail message, including any attachments, is for the sole use of the intended recipient (s) and may contain confidential and privileged information.
