Hi all ,

I am trying to configure ip range to one of my interfaces in my linux router.

I am issues when i try like below.

#ip address 11.1.1.0/24
% host portion of interface/gateway IP address cannot be 0 or subnet broadcast address

Here host portion means first three octets , and why it says like cannot be '0' and throws error.

My intention here is like give 11.1.1.1 to router and allow ip's of range 11.1.1.2 to 11.1.1.253 . So where am i going wrong here?.

If i give below ips it works fine.

[local]Ref_5d01-ipos1(config-if)#ip address 11.0.0.1/24

So where am i going wrong.

thanks
Rama

On a class C network, /24, the 11.1.1 is the network and .0 is the host. When you assign the ip address of 11.1.1.1/24 to the interface the system knows that it belongs to the network 11.1.1.0. You do not assign a network range to an interface you assign an ip address.
