The question states that the 150.100.40.0/24 should be NAT'ed. Because the expectation is that this would then be a private network you wouldn't be announcing it to the rest of the network. Thus you add the rest of the interfaces individually. Of course you could accomplish this many ways. You could add them back using the interface or network commands.
If you announce the network if someone sends traffic to the network the response will be NAT'ed thus causing unwanted issues.

Does it make a difference if you leave it? It shouldn't break the NAT, but I haven't tested. Looking forward to a response on this one as well.

What I don't understand, and I've seen this previously, is why we need to change the OSPF configuration. Currently, it's configured for all interfaces. The section requirements only mention not natting the f0/1. The recommended configuration is to remove the 0/0 for OSPF configuration, and only add back the Serial, Loopback, and F0/1 (excluding the NVI and F0/0. Why is that? router ospf 1 log-adjacency-changes network 0.0.0.0 255.255.255.255 area 0 Regards, Jay McMickle- CCNP, CCSP, CCDP, MCSE http://mycciepursuit.wordpress.com/ _______________________________________________ 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.
