Hi @sales2161,
I think this output is confusing, especially when it looks like this:
172.16.0.0/24 is subnetted, 1 subnets
C 172.16.1.0 is directly connected, FastEthernet0/0
On IOS 15, the output is different:
R1#show ip route
Gateway of last resort is not set
172.16.0.0/16 is variably subnetted, 2 subnets, 2 masks
C 172.16.1.0/24 is directly connected, GigabitEthernet0/1
L 172.16.1.1/32 is directly connected, GigabitEthernet0/1
192.168.12.0/24 is variably subnetted, 2 subnets, 2 masks
C 192.168.12.0/24 is directly connected, GigabitEthernet0/2
L 192.168.12.1/32 is directly connected, GigabitEthernet0/2
It now shows 172.16.0.0/16 as “variably subnetted” together with the network address and IP address. This output is easier to read.
