IP static route summary query 3.

Question:

In my Lab environment cisco ios commands in GNS I have connected two 7200 series router through fastethernet on router A I have given IP adress 192.168.10.54 and router B I have given IP address 192.168.10.53 and default route as 0.0.0.0 0.0.0.0 192.168.10.53 and when I run the command on router A it shows result as follows  "C  192.168.10.52/24 is directly connected ,Fast ethernet 2/0".

So I need to know why it's showing the result of .52 at last why not .53 or .54 at last what is the reason it's showing .52 which I have not mentioned in my IP address.

Answer:

Then thats the correct thing you are seeing. I have showed this to you on my previous update:

If you are using the /30 then the subnet would be displayed.

R1(config)#int f1/0

R1(config-if)#ip address 192.168.10.54 255.255.255.252

R1#show ip route

     192.168.10.0/30 is subnetted, 1 subnets

C       192.168.10.52 is directly connected, FastEthernet1/0 <<<< 52 is displayed.

In your scenario:

===========

10.255.222.52 is the subnet and followed by the host ids.  ( 10.255.222.53 & 10.255.222.54 will be the two host which can be on .52 subnet hence it only shows you the .52 in the routing table.
