Hello,

 

the mask 255.0.0.0 puts both networks in the same range. You need to use 255.255.255.0 as subnet mask for both networks.

Hi,

As you know that IP address 11.xx.xx.xx is A class address and default subnet mask is 255.0.0.0 means this IP range from 11.0.0.1 to 11.255.255.254 in a single subnet.

 

As you want:

when i give 11.67.80.1 gigabit0/1 subnet 255.0.0.0 

Then use the Subnetting concept and make it those subnets as:

11.67.79.1/255.255.255.0 on Gig 0/0

11.67.80.1/255.255.255.0 on Gig 0/1
