ip subnet zero is required when you want to use subnet zero i.e. 192.168.0.1
with a subnet mask of 255.255.255.0 is the zero subnet and can only be used
when you have ip subnet zero command. ip classless is another for routing,
with this if a packet comes in for a destination which is not exactly known
then it is dropped without the command ip classless on. With it on the same
packet will go to the "nearest matching route".

Subject: classless behaviour
Hi,
To configure classless behaviour, we use "ip subnet-zero" and "ip
classless".
I never understand them, even after reading Doyle's bible.
* When do we need them ?
* If we don't use them, what will happen ?
* Is there good example to show their effect ?
Thank you in advance.
Bill
