You have to enter both:
ip classless
ip subnet-zero
from the config prompt to allow for non-standard (CIDR) netmask boundaries.
Hope this helps.

Subject: [nsp] Can't change IP address on 1601
I wonder if someone can help me. I'm trying to change the IP address on the
e0 interface of a 1601 router and when I enter the commands, I get a message
telling me that the netmask is invalid. The current IP is a public IP using a
/24 mask and I want to change to a private (10.0.0.something) class C IP and
mask. I was able to make the change on one of the routers but the second box
won't take the change but tells me that the mask (and in the error message it
says /24 mask) is invalid for the IP address. The specific command I tried
is:
IP address 10.0.0.221 255.255.255.0
Any insight would be greatly appreciated.
Thanks,
Eric Bloom
