I am trying to configure a Cisco 3945. When enter the command:
ip subnet-zero
and the do a
sh run
The running config does not show that subnet-zero is active. I even tried
sh run | inc subnet
and still see nothing. Why is the command not taking? I just want to configure the router with 2 IP addresses and a gateway of last resort.
Example:
Gige 0/0
ip address 192.168.1.1 255.255.255.252
duplex full
speed 1000
Gige 0/1
ip address 10.1.1.1 255.255.255.224
duplex auto
speed auto
For some reason when I configure Gige 0/1 it tells me that /27 is not allowed even though I set
ip classless
Can anyone please assist? Thanks!

ip subnet-zero in enabled by default.

Can you provide the exact error during the configuration along with the entire config?
Thanks

Oops! guess thats what happens when you make your configuration checklist at 3am
Thanks for the help!
