Can someone give a gerneral explanation on these two commands?
ip subnet-zero
ip-classless
What do they do and why would you use them?
Thanks.

this command the router would still do a longest bit
match but doesn't understand subnets, and would check for a subnet if it
is not local to your router it would be dropped.
Ip subnet-zero- This allows the use of the zero subnet and the ip
addresses in that range. take for instance you have
determining valid subnetworks it used to be true all were valid
accept
the all 1's subnet and the all 0's subnet. In an environment where all
devices are compatible, I understand, that by using the configuration
command "ip subnet-zero" it enables the use of the all 0's subnet. The

question I ask then, wouldn't that leave the all 1's subnet still an
invalid
subnet even when using the previous mention
Hi all,
What is the best way to determine if an ip/subnet is an ip subnet-zero
address?
Thanks,
Peter

Strongly discouraged as all ones ip-subnet. Otherwise, you'd refer to the
classfull address.

Report misconduct
Check the IP address to see if it falls on a network boundary.. eg.
192.168.1.16 with 28 bit mask
192.168.1.32 with 28 bit mask
150.49.5.136 with 30 bit mask
of course assuming ip subnet-zero command is used.. you will not get the "bad
mask" error..
"Gert Jan" [EMAIL
In IP rules it is not possible to use a zero-subnet.
If you wanna overrule this, use it anyway (and why not :-) ) and place a
interface anyway in it you must invoke the ip subnet-zero command.
Try subnetting a IP subnet and without the ip subnet-zero command set an ip
address on a interface
Hi,
Had a question on ip subnet-zero? It is on by default when you first
configure a router? Why would I want it or better still, why would I not
want it?
Please advise.
Thank you.
Kind regards,
Niraj
